                                LQ
              Letter quality for dot matrix printers.

1. Introduction.

    LQ is a program for the IBM PC and compatible computers
which will allow you to produce high-quality text on inexpensive
dot matrix printers.  Most 9-pin printers are supported, but you
may have to install or create a configuration file (see Section 5)
if yours deviates significantly from an Epson.

    LQ offers these features:

  1. LQ can be 'locked' into memory to function inconspicuously
     with your favorite word processor or other program, or it can
     be used only as needed to process disk files.

  2. Most control sequences for turning on special modes
     (boldface, underline, superscript, etc.) will produce the
     corresponding results with LQ, so you may not have to modify
     your word processor to accommodate LQ.

  3. LQ includes a print spooler which can be set to any length
     from 1 - 400K characters.  The spooler has been customized to
     work with LQ's long graphics sequences very efficiently
     (using about 1/40 the space required by a conventional
     spooler); you can continue using your computer for other
     tasks while documents print in the background.  If you use
     single sheet feed, LQ will interrupt your work to prompt you
     to change paper then return to you to the point at which you
     were interrupted.

  4. The spooler and several of LQ's options can be controlled
     using a 'pop-up window' which is available at any time.  This
     is particularly convenient for toggling letter-quality mode
     on and off and for flushing the buffer to abort a printout.

  5. Special modes such as proportional spacing, extra-large and
     graphics printing are available.  A letterhead editor is
     included for making customized logos to be printed with LQ.

  6. Four fonts are available at any time, and others can be
     swapped into memory when desired.  You can switch between
     these fonts using codes in your text or by using the LQ
     Control Window.

  7. You can modify an existing character set or edit your own
     from scratch using the EDCHAR program included in the
     package.

    You will probably want to take a look at LQ's output before
reading about all the details.  Following is a procedure to get
some quick results if you have an Epson-compatible printer; if
yours is different, skip this test and read on.

  1. Boot DOS.
  2. Insert the LQ disk and type LQDEMO.
  3. Turn on your printer and press a key when prompted.

    If you want to experiment a little with LQ now, try the
following:  type 'LQ' at the DOS prompt to load the program into
memory, then run any other program (such as a word processor)
which generates printed output.  At any time you can bring up the
LQ menu by pressing both shift keys simultaneously.  If your
output is garbled, don't panic yet - read on!

Note:  The file READ.ME describes revisions to LQ and other
important information.  To view this file on the screen enter GO;
to obtain a printed copy enter COPY READ.ME PRN.


2. LQ installation.

    There is a good chance that LQ is already configured properly
for your use; if you have an Epson-compatible printer we recommend
that you skip this section on first reading of the manual and come
back to it later.

    There are two levels of installation which may need to be
performed in order to use LQ.  You should configure your word
processor or other application for an Epson MX 80 (or IBM Graphics
Printer) if it uses control codes to exploit a printer (to print
italics, emphasized print, etc.), and you should run LQINST if you
have a printer which is not Epson-compatible (or if you want to
change the size of the buffer, assign a different key combination
to bring up the LQ Control Window or change the default character
sets used by LQ).

    LQ will make your printer appear to a word processor as an
Epson MX 80 (or IBM Graphics Printer) when printing in the letter-
quality mode.  Most word processors will let you choose a printer
when a document is printed, so you can maintain one printer
description file for draft mode (based on what your printer really
is) and another one for LQ mode.  For example, PC-Write gives the
prompt

    Print control file name (Esc:exit Enter:none):

and MultiMate lets you select a PAT (Printer Action Table) file
when documents are printed.

LQINST.

    LQINST alters the LQ.COM program, so it is wise to make a copy
of the LQ disk before starting the installation procedure.  Insert
a working copy of the disk in your computer's default drive and
LQ installation                                                  3

enter 'LQINST'.  You will be prompted to enter the disk containing
the file LQ.COM; since this file is on the distribution disk, no
disk exchange is necessary.  Throughout this installation
procedure you can ignore messages to insert disks if you are
working with a copy of the distribution disk; later on if you use
eparate disks for different character sets or other LQ data you
should swap disks as prompted. The screen should now show:
_______________________________________________________

    LQ installation menu:

    1. Change default character sets.

    2. Change printer parameters.

    3. Change keys for LQ window.

    4. Change buffer size.

    5. Quit.

          Which? (1 - 5)
_______________________________________________________

Each option will be described below, but if this is your first use
of LQ you will probably be content to use only option 2 (and that
only if your printer is not Epson-compatible).

Option 1:  Change default character sets.

    The LQ.COM program includes four character sets within its
code; initially these are the sets COURIER, COURITAL, HELV and
PALATINO.  (See Section 9 for a listing of these and other
available sets.)  If your use of other sets is infrequent it is
best to load them explicitly using the LQ parameter line (see
Section 6) but if you would like different sets to be used by
default then this installation option is in order.  Installation
of a new set is a two-step process: first you indicate which set
you want to install, then you assign it the number (1 - 4) used to
turn on the set.

    After this option is selected you are shown a list of
character sets and prompted to enter the number of the set to
install:
_______________________________________________________
LQ installation                                                  4


     1  COMPUTER     9  HELVITAL    17  ROMAN2
     2  COURIER     10  HOLLOW      18  ROMANITA
     3  COURIER2    11  IBM1        19  SANS2ITA
     4  COURITAL    12  IBM2        20  SANSITAL
     5  GOTHIC      13  MAIN        21  SANSSER
     6  GREEK       14  MAINITAL    22  SANSSER2
     7  HELV        15  PALATINO    23  SCRIPT
     8  HELV2       16  ROMAN       24  SPIRAL

      Enter number of set to install:
       (press <Enter> to quit)
_______________________________________________________

After you enter the number of the set to install you are prompted

    Enter installed character set number (1-4):

This second number is used in control sequences, in the LQ
parameter line, or in the LQ Control Window to switch to the
corresponding set.  Any of the four sets can be used at any time,
ut the first two sets have special roles of which you should be
aware.  The first set is used by default, so it should be the one
you use most often.  The second set can be turned on by the
control sequence you normally use to switch to italics, so it is
best (but by no means required) to make it the italicized version
of the first set.  For example, you could make the first set
SANSSER and the second SANSITAL.

    After you enter the 'installed character set number' the cycle
is repeated:  you are again prompted to choose a set to install.
You can continue until all four sets are changed, or you can
retain previous sets for those you don't change.  When you are
finished, press <Enter> without typing a number.

    The changes you make in this and other LQINST options are not
made permanent until you exit the program, so don't worry about
doing anything lethal.  Even if you do save a revised version of
LQ.COM, you can always run LQINST again to restore it to the way
it was.

Option 2:  Change printer parameters.

    The second option lets you change the default Epson printer
parameters to those for another printer.  Printer parameters are
contained in files with the suffix 'PAR' which you may edit or
create yourself.  (See Section 7.)  If you are a registered LQ
user and experience problems installing a non-Epson printer, we
will try to create a parameter file for you on request.  See
Section 7 for a description of the printer requirements for using
LQ.

Note:  After you have performed this installation process, your
LQ/printer combination will act like an Epson MX or IBM Graphics
Printer regardless of what kind of printer you actually have.
When using LQ you should make certain that your word processor or
LQ installation                                                  5

other application 'thinks' you have one of these models.  Again,
see Section 7.

    When you select this option you are prompted to insert the LQ
disk, then you are shown a list of all parameter files on the
disk.  Currently these are

     1  EPSON
     2  IMAGE
     3  PROPRINT
     4  CITOH
     5  STAR

A given file may work for more than one type of printer; for
example the Epson parameters are appropriate for the IBM Graphics
printer.  Enter the number of your choice.

    Some experimentation may be required to find or create the
right file.  Rest assured that you won't do any harm by installing
the wrong parameters; your printer may appear to run amuck, but
the only cost is the paper.

Option 3:  Change keys for LQ window.

    There are four shift keys on the PC keyboard: Ctrl, Alt, Left
Shift, Right Shift.  Many background utilities use combinations of
these keys to spring into action; for example, 'Sidekick' normally
requires that the Ctrl and Alt keys be depressed simultaneously.
The LQ Control Window is normally brought up by pressing the left
and right shift keys together, but you can change this to any pair
of shift keys.  Use LQINST to make this change permanent or use
the K option to pass the key combination (temporarily) on the LQ
parameter line (see Section 6).

    When the third option is selected the following screen is
displayed:
_______________________________________________________

    Key installation.

    The pop-up window used to control LQ operation is normally
    brought up by pressing the right and left shift keys
    simultaneously.

    You can change this combination to any two of the following:

    Ctrl

    Lft Shift         Rt Shift

    Alt


    Press the two keys you would like to use:
_______________________________________________________

Using LQ in the resident mode                                    6

As soon as you press the desired key combination, you are returned
to the main menu of LQINST.

Option 4:  Change buffer size.

    Printing in LQ mode is slow enough that you will not enjoy
sitting idly by waiting for a printout to finish.  LQ includes a
'print spooler' for printing in the background while you use your
computer for other tasks.  The default size of the buffer used by
this spooler is 16K, which will accommodate about six pages of
text.  You can change the buffer size to any value from 1K to
400K;  when you select option 4 you are prompted to enter this
value.  For example, if you want a 20K buffer just enter the
number 20.

Option 5:  Quit.

    The last option is used to exit from LQINST.  If you have made
changes you are prompted

        Save modifications? (Y,N)

If you press 'N' then LQ.COM is unchanged, otherwise all changes
you have made in this LQINST session are made permanent.  (You can
always run LQINST again to make further changes.)


3. Using LQ in the resident mode.

    The preferred way to use LQ is in the 'resident' mode in which
LQ stays in memory while other programs are run; this mode offers
print spooling and the Control Window for changing LQ's
parameters.  The disadvantage of the resident mode is the memory
consumption:  with the default 16K buffer the program uses about
90K of RAM.  If you don't have enough memory to run other programs
with LQ installed you should use the file mode described in the
next section.  While the latter mode is less convenient you can
still obtain exactly the same printouts.

    If you want to use LQ as a resident program for only part of
your session on the computer you can enter
    LQ R
to remove LQ from memory.  This works only if no other resident
programs have been loaded above LQ, so if you plan on using this
technique load LQ last (after installing other programs such as
Sidekick).

    To load LQ in the resident mode simply type 'LQ' at the DOS
prompt.  A variety of options can be set by adding parameters to
this entry; for example
    LQ C1'SANSSER'
loads LQ and replaces the first character set with SANSSER.SET.  A
full description of command line parameters is given in Section 6.

    Once LQ is loaded you can generally use your accustomed
software with no changes other than improved printouts.  (You may
Using LQ in the resident mode                                    7

have to change your word processor's printer description table to
accommodate an Epson MX 80 or IBM Graphics Printer; see Section
2.)

    Some interaction with LQ can increase its effectiveness.  This
section describes how to use the Control Window and print spooler
to really master your printer.

The spooler.

    A print spooler is a program which directs pending printouts
to an area of memory (buffer) and sends characters from this
intermediate storage to the printer only when the computer is
relatively idle.  The process takes place in the background so
that you can use your word processing program or other application
without interruption.  A number of fine print spooling programs
are available, some of them public domain.

    LQ obtains its high quality print by printing in the 'graphics
mode', and this presents special difficulties for a conventional
spooler.  Without LQ a character is sent to the printer as a
single byte or unit of information, but LQ requires about 40 bytes
to 'draw' a single character.  A single page of text can balloon
to over 100K bytes, more than enough to fill the typical buffer.
Once the buffer is full a spooler no longer yields any advantage -
other activities must stop until the backlog subsides.

    LQ includes an integrated spooler with a default buffer of
16K.  Characters are spooled in the standard compact form and
expanded to graphics in small increments.  The default buffer size
will ccommodate about six pages of text and you can increase the
size to as much as 400K (see Section 2).  The spooler also works
in draft mode (LQ loaded but turned off), so it may be attractive
to keep LQ in memory even if your demands for letter-quality print
are infrequent.

    If you find that a pending printout contains an error (such as
spelling or formatting) you will probably want to abort the
printing and correct your document.  To do this you must 'flush
the buffer':  you must tell LQ to stop printing and to ignore the
presence of any remaining characters in its queue.  This entails a
single keypress in the LQ Control Window described below.

The LQ Control Window.

    There are three ways to select options in LQ:

in the LQ command line (as when you enter
    LQ C1'SANSSER'
at the DOS prompt to load the character set SANSSER),

using control sequences embedded in your text (such as
  <Esc> <Esc> '2'  to switch to character set 2),

using the LQ Control Window.

Using LQ in the resident mode                                    8

When LQ is in the resident mode you can bring up the Control
Window by simultaneously pressing the right and left shift keys
(or another pair of shift keys installed with LQINST - see Section
2).  You'll see the following menu:

    Buffer   0% full.  Flush?  Yes
    Current character set:     1
    Wait at form feeds?        No
    Proportional print?        No
    Lines per page:            66
    LQ mode enabled:           Yes

The cursor is initially positioned at the 'Yes' on the first line.
The keys you may use are:

down arrow:  move down a line,
up arrow:    move up a line,
space bar:   change this option,
'A':         advance the printer a little,
<Esc>:       exit this menu.

The options you can change are:

Flush the buffer:  If you press the space bar on this line, any
  pending printout is aborted.  Use this option to remove an errant
  document from the buffer.

Change character set:  The character set number is rotated in the
  set 1,2,3,4.  If character set number two is currently in use and
  the space bar is pressed, then set number three will be used at
  the next opportunity.

Wait at form feeds:  The space bar toggles the status of LQ's
  response to a form feed character (ASCII code 12).  When this is
  set to 'Yes', LQ will interrupt a program in progress after a
  form feed is received and prompt you to change paper.  In
  response to the prompt, <Enter> will continue printing and <Esc>
  will abort printing.  In either case you are returned to the
  program you were using without interference.

Proportional print:  You can set proportional print on or off.
  Using proportional print the sequence 'iiii' will occupy less
  space than 'MMMM'.  This makes text more attractive but disrupts
  the spacing of tables and text separated by white space.  Try
  this option to see if it is appropriate for your document style.
  (Read the file LQPCWRIT.DOC for a description of using
  proportional spacing with the PC-Write (Shareware) word
  processor.

Lines per page:  The default line spacing, and the one normally
  expected by other programs, is 66 lines per page.  If you want to
  change this, press the space bar and then enter the new value.
  Because of physical limitations of your printer, not all these
  values are possible; for example, if you  enter the number 58 you
  may see this rounded to 59 (the nearest acceptable value).

Using LQ in the resident mode                                    9

LQ enabled:  The LQ mode can be toggled on and off.  In the 'off'
  setting your printer will operate as if LQ were not installed,
  except that print spooling will still be functional.

Advance:  Pressing 'A' any time the Control Window is open will
  result in a small (1/216") advance of the paper when the window
  is closed.  With many printers the first line of a printout may
  appear smudged; advancing the paper with this option will fix the
  problem.  This is done automatically in the LQ file mode (see
  Section 4) or when LQ is loaded in the resident mode (if the
  printer is on).  You can also perform this action by embedding
  the <Esc> <Esc> B control sequence in your text (see Section 5).

When you are finished using the Control Window, press <Esc> to
return to your previous application.
4. Using LQ in the file mode.

    When LQ is invoked with the 'F' option a file is printed in
letter quality but LQ does not remain resident.  An example of
this use is
    LQ F'MYFILE'
which prints the file MYFILE.  The primary reason for using the
file mode is to accommodate systems with insufficient memory for
using LQ in the resident mode.  (Another use is for using LQ in
batch files for printing letterheads and other designs; see
Section 11.)  Since LQ is not resident in the file mode no
spooling is performed and you must wait for a printout to finish
before using your computer for other tasks, or you must use the
DOS PRINT command as described below.  Also, the Control Window
is not available in the file mode.

    You can use a variety of options in the LQ command line; for
example
    LQ F'MYFILE' W
prints MYFILE and waits at form feeds for paper to be changed.
See Section 6 for a complete description of avaiable options.

    When using the F(ile) option, you can stop printing at any
time by pressing a key; you will be asked if you want to abort
the printout or continue.

    The way you create files to be printed by LQ varies from one
application to another.  Most word processors store documents in
special formats which make sense only to the program itself;
let's call these 'source' documents.  You want to print not these
but rather the 'output' documents that correspond to the
characters which would normally go to the printer.  For example
when one asks WordStar to print a file the program prompts
    Output to disk file?
and gives the user a chance to channel output to a file which
would otherwise go to the printer.  Such an output file is also
called an ASCII file since it contains only standard ASCII
character codes.  (See Appendix B.)

    PC-Write is another popular word processor which produces
ASCII files easily.  The command
Using LQ in the file mode                                       10

    PR MYFILE
formats and prints the source document MYFILE, and the command
    PR MYFILE YOURFILE
sends the output to the second file YOURFILE instead of a
printer.  PC-Write is an outstanding Shareware product; the
distribution disks can be obtained for $16 from Quicksoft, 219
First N. #224, Seattle, WA 98109, 206/282-0452.

    The vast majority of word processing, database and
spreadsheet programs on the market can produce ASCII files;
consult your program's manual for details.

    If you have a previously-created text file 'printout' you
want to print in a letter quality mode you can take three
different approaches.
       LQ F'filename' [parameter list]
will function as described above.  You can enter
      COPY filename PRN
if LQ is resident in memory.  The final alternative requires a
lot of disk space (preferably a hard disk) but has the advantage
of printing in the background without tying up memory as when LQ
is resident.  If you enter
       LQ F'filename','filename2'
(no spaces after the F) then all the graphics characters which
would have been printed go to the second file 'filename2'
instead.  This file will be about 40 times as big as the first
file, so make sure you have room on your disk before proceeding.
Assuming that you have previously created the program BPRINT.COM
you can now enter
       BPRINT filename2
without LQ being resident.  You can continue to use your computer
as your file is printed, and you won't sacrifice the RAM that LQ
would otherwise occupy.  (See Section 11 for a full description
of creating and using BPRINT.)  If the file is short (as with a
letterhead) you may want to type
       COPY/B filename2 PRN
(again without LQ being resident) rather than spooling the file
with BPRINT.  (The '/B' option lets the graphics codes used by LQ
go to the printer without interference from DOS.)

    In any of these three cases you may want to add additional
control codes within the text before printing; Section 5 contains
a list of control codes and their functions.  For example,
suppose you have used your word processor to create an output
file with the lines
    This is a test.
    This is only a test.
The control sequence used to initiate a line of large characters
is '<Esc> <Esc> L'; let's look a couple of ways to insert these
codes before the first line.  If you have Sidekick on your
system, you can enter a control code such as <Esc> by first
pressing <Ctrl P>, so you would position the cursor at the start
of the first line and type
    <Ctrl P> <Esc> <Ctrl P> <Esc> L
(The same technique works with WordStar.)  A more universal (but
less convenient) method is to use EDLINE.COM, the line editor
Using LQ in the file mode                                       11

which is included with your DOS system disk.  You can edit a
given line in the same way you edit a line at the DOS prompt;
here is a summary of line editing functions from the DOS User's
Guide:

  DOS           Description
  Editing Key
  Ins           Allows you to insert characters within
                a line.
  Del           Deletes one character in the input
                buffer.  The character in the buffer is
                not displayed and the cursor does not
                move.
  Esc           Cancels the line currently being
                displayed.  The buffer remains
                unchanged.
  F1 or ->      Displays one character from the buffer
                each time it is pressed.
  F2            Displays all characters up to a
                specified character.
  F3            Displays all characters in the buffer.
  F4            Displays all characters after and
                including the specified character.  F4
                is the opposite of F2.
  F5            Accepts the line you edited as the
                current buffer line.

    Assuming you had saved the previous file under the name
MYFILE, you would begin your EDLIN session by entering
    EDLIN MYFILE.
Find the number of the line you want to edit by using the List or
Search commands (see the DOS manual for details), then enter this
number to edit the line.  In this case we know in advance that we
want to edit the first line, so we would enter the number '1'.
The screen should show
    1:*This is a test.
    1:*
Control characters can be entered by using the <Ctrl V> prefix;
for example, <Ctrl T> can be entered by typing <Ctrl V> T, and
<Esc> can be entered by typing <Ctrl V> [.  Press Ins to enter
the insert mode, then type <Ctrl V> [ <Ctrl V> [ L.  Press F3 to
display the rest of the buffer ('This is a test.') and press
return.  To save the modified file, enter 'E'.

    Many word processors (including PC-Write) allow the direct
entry of control codes, so you may not need to go through such an
extra step to use LQ's special features.  The READ.ME file gives
a description for some programs; consult your word processor's
manual for details.


5. Control sequences.

    A 'control sequence' in a document is a sequence of codes or
characters which has a special meaning to your printer (or the
program controling it), and which changes the way in which
Control sequences                                               12

subsequent characters are printed.  You have probably used such
codes for some time, perhaps without realizing it.  When you tell
your word processor to print a book's title in boldface or to
print a subscript, you are telling your software to insert the
appropriate control characters for performing these functions.

    Regardless of what kind of printer you are using, LQ will
make your printer appear to a word processor or other application
as an Epson MX 80 (or IBM Graphics Printer).  Assuming that you
have installed your application program for this printer you can
get extensive use out of LQ without any direct involvement with
control sequences.

    If your program does not support all the features of an Epson
MX 80 (italics, underlining, emphasized print, superscript
/subscript, etc.) or if you want to use some of the special
features of LQ (large characters, proportional print, graphics),
you will need to insert control codes on your own.  You can
always use EDLIN.COM (a line editor included with your DOS system
disk) to do this; you probably have an easier way at your
disposal.  Read Section 4 for details on inserting control codes.

    If the LQ feature you want to use will not change during a
printout, you can request it in the LQ command line rather than
using control sequences.  For example, 'LQ C3' turns on character
set number three (out of the four in memory) as an alternative to
'<Esc> <Esc> 3'  within your document.  The LQ command line
options are described in the following section.

    You can also use the Control Window to use some LQ features;
see Section 3.

    In addition to inserting control codes or using the Control
Window to switch character sets, one other technique is
available.  Most word processors have a way of turning on
italics; since the italic set is expected to be the second of
LQ's four sets, you can change to any second set by turning on
italics.  If you want to use this method, have LQ load the
desired alternate character set with a command such as
    LQ C2'SANSSER'
(which loads SANSSER.SET as character set number 2, replacing
italics).

Control functions available in LQ.

    Following is a list of LQ functions which may be used within
a document using control sequences.  Most of these duplicate
standard Epson control codes; functions which differ from the
Epson standard (generally beginning with <Esc> <Esc>) are
indicated with an asterisk.  Each control sequence is shown in
two forms: the sequence of keys to press, then the corresponding
sequence of (decimal) ASCII codes.  For example,
  <Esc> 'E' = 27,69
indicates that the sequence consists of the escape key code
ollowed by the code for the capital E character.  The standard
codes are usually inserted automatically by a word processor when
Control sequences                                               13

the associated mode is requested, but the additional LQ modes
must be added explicitly.

  Turn on double-wide print:
  <Ctrl N> = 14

  Turn off double-wide print:
  <Ctrl T> = 20

  Turn on underline:
  <Esc> '-' N = 27,45,N    where N corresponds to any code except
   0 or '0'.  For example, use
   <Esc> '-' 1 = 27,45,1.

  Turn off underline:
  <Esc> '-' N = 27,45,N    where N corresponds to either '0' or
   0.  For example, use <Esc> '-' '0' = 27,45,48.

  Set line spacing to N/216":
  <Esc> '3' N = 27,51,N    where 1 <= N <= 255

  Turn on italics (character set #2):
  <Esc> '4' = 27,52

  Turn off italics (turn on set #1):
  <Esc> '5' = 27,53

  Sets line spacing to N/72":
  <Esc> 'A' N = 27,65,N    where 1 <= N <= 85

  Turn on boldface:
  <Esc> 'E' = 27,69  or  <Esc> 'G' = 27,71

  Turn off boldface:
  <Esc> 'F' = 27,70  or  <Esc> 'H' = 27,72

  Superscript:
  <Esc> 'S' # = 27,83,#   where # corresponds to '0' or 0.  For
   example, <Esc> 'S' '0' = 27,45,48.

  Subscript:
  <Esc> 'S' # = 27,83,#   where # corresponds to any code except
   0 or '0'.  For example, use <Esc> 'S' '1' = 27,45,49.

  Superscript/subscript off:
  <Esc> 'T' = 27,84

* Switch to character set n (1 <= n <= 4):
  <Esc> <Esc> 'n'.  For example, <Esc> <Esc> '3' =
   27,27,51  turns on character set number 3.

* Advance paper a little to put tension on paper (recommended for
   preceding first line of printout; this function is performed
   automatically when the F(ile) option is used.):
  <Esc> <Esc> 'B' = 27,27,66

Control sequences                                               14

 Turn on graphics mode:
  <Esc> <Esc> 'C' = 27,27,67
   The graphics mode suppresses the normal space between
   characters and between lines so that you can produce
   letterheads and other pictures.  See Section 11 for details.

* Turn off graphics mode:
  <Esc> <Esc> 'D' = 27,27,68

* Turn on elite (12 cpi) printing:
  <Esc> <Esc> 'E' = 27,27,69
   The best character set for using elite is HELV (character set 3
   in the default installation), so you may want to turn on elite
   printing in this set with
     LQ MN C3
   (See Section 6.)  Other narrow sets are appropriate for elite,
   but don't use the wider sets such as COURIER (default set 1).
   Proportional spacing is not supported in elite - if such
   spacing is desired, use the same set in pica mode.

* Turn off elite printing, restore pica (10 cpi):
  <Esc> <Esc> 'F' = 27,27,70

* Turn on triple-high (large) characters in the current set:
  <Esc> <Esc> 'L' = 27,27,76
   The large mode stays on for all lines until <Esc> <Esc> 'M' is
   received.  The line containing this second sequence
   is printed in the normal size.

* Turn off triple-high characters:
  <Esc> <Esc> 'M' = 27,27,77

* Turn on proportional spacing:
  <Esc> <Esc> 'P' = 27,27,80

* Turn off proportional spacing:
  <Esc> <Esc> 'Q' = 27,27,81

* Set line space to n units (where one unit is either 1/144" or
   1/216" depending on the smallest line advance your printer
   supports):
  <Esc> <Esc> 'S' # = 27,27,83,#
   where # is the number (from 1 to 255) of increments desired.
   For example, the smallest Epson line advance is 1/216", so
   <Esc> <Esc> 'S' '$' = 27,27,83,36 sets the line space to
   36/216" = 1/6".  It is generally easier to use the L(ines per
   page) parameter when activitating LQ or the lines per page
   option in the Control Window to determine the number of lines
   on an 11" page.

* Wait for key to be pressed at page breaks:
  <Esc> <Esc> 'W' = 27,27,87

* Don't wait at page breaks (the default):
  <Esc> <Esc> 'X' = 27,27,88

Control sequences                                               15

Other ASCII codes.

    LQ supports IBM graphics characters (ASCII codes above 127).
Codes 128-159 correspond to the first 32 characters in set number
3 and codes 160-255 to all of set number 4.  To use graphics
characters the sets IBM1 and IBM2 should be installed as sets 3
and 4.  For consistency you may want to use the sets MAIN and
MAINITAL for the first two sets as well (though this probably will
not be important).  Hence you can load LQ with
     LQ c3'IBM1' c4'IBM2'
or   LQ c1'MAIN' c2'MAINITAL' c3'IBM1' c4'IBM2'.
You can make these assignments permanent with the LQINST program.
(If you are using PC-Write and want to use foreign characters, put
a '$A' in your PR.DEF file.)

If you are using the graphics characters to create borders or other
designs you may want to change your line spacing to avoid gaps in
vertical patterns.  Your word processor may take care of this
automatically; if it doesn't, use the control sequence
  <Esc> 'A' 8 = 27,65,8
to change the line spacing to 8/72".

    Three additional control codes besides those described above
are recognized by LQ: 10 (line feed), 12 (form feed) and the 13 10
(carriage return, line feed) sequence.  All other control codes
(ASCII codes less than 32) besides those listed above (or the
substitutes given in a parameter file) are ignored.  In
particular, LQ does not support the backspace character, nor does
it support the carriage return code by itself.  The most common
situation in which this causes a problem is when a word processor
tries to bold face or underline text by backspacing (or sending a
carriage return) and retyping the text or the underline character.
If your printout looks something
  like this   like this
or
  like this   ________
then your word processor is responsible - it thinks your printer
is 'dumber' than it really is and is not fully exploiting it.  The
solution is to convince your word processor to turn bold face or
underlining on and off with the control sequences described above.
Usually this can be done as part of the installation process for
your word processor or by explicitly entering control sequences
yourself (see below); if this process is not clear you may want to
call the technical support department of the company that
distributes your word processor.  Most programs won't have this
problem to begin with, so don't worry unless your printouts appear
to stutter as illustrated above.

    Entering control codes directly is a last resort; ideally your
word processor should do this for you.  Here are some examples of
control code entry:

In WordStar you can insert control characters by pressing <Ctrl P>
first.  For example, the sequence to turn on emphasized printing
is <Esc> 'E', so you would press
 <Ctrl P> <Esc> E
Control sequences                                               16

(a total of 3 keystrokes).  You will see
 ^[E
on your screen.  If you want to underline the last word in 'This
is a test' you will see
  This is a ^[Etest^[F
(<Esc> 'F' turns off emphasized print.)

In PC-Write you can enter any code by using the <Alt> key along
with the numeric keypad.  For example to enter <Esc> (which has an
ASCII code of 27) press down on <Alt> and without releasing this
key press '2' and '7' on the numeric keypad.  Now release <Alt>.
(This should never be necessary - you can always modify PR.DEF to
exploit LQ.  See LQPCWRIT.DOC for details.)

In WordPerfect you can insert control codes in your document by
using angle brackets.  For example, to switch to font 3 you can
insert <027><027><051>, which will send <Esc> <Esc> '3' to LQ.


6. The LQ parameter line.

    An easy way to set one-shot options LQ is in the command line
typed when LQ is installed.  For example if you want proportional
spacing for all your printing,
    LQ MP
will install LQ with the proportional mode turned on.  The 'LQ'
file must be loaded each time an LQ command is given, so if LQ is
not on the default drive, give the full path name for LQ, e.g.
B:LQ MP (if LQ is on the disk in drive B).  You select as many
options as you like in a single line by separating parameters with
spaces.  For example,
    LQ MPE F'MYFILE' W
turns on proportional spacing, emphasized printing for the file
MYFILE, pausing at form feeds.  This section lists all command
line options.  Parameters are shown in upper case, but you can mix
upper and lower case freely.

B
  Set the buffer size (1 - 400) in K bytes.  For example LQ B64
  dedicates 64K of RAM to the print spooler.  (The default is
  16K.)  The command LQ BF flushes the buffer.  (It is easier to
  flush the buffer using the Control Window.)

  The buffer can be installed only when LQ is first loaded.  To
  change the buffer size, first remove LQ (see the R option below)
  then load again.

C
  Specifies a  character set in memory, or loads a new set.  Four
  sets are embedded in LQ, and the first of these is normally used
  as the default.  LQ C4 switches printing to the fourth set; when
  used in this way, 'C' can be followed by one of the digits
  1,2,3,4.  The standard sets installed in LQ are:
LQ parameters                                                   17

    1 - COURIER.SET
    2 - COURITAL.SET
    3 - HELV.SET
    4 - PALATINO.SET
  These defaults can be changed with the LQINST program described
  in Section 2.  You can see a list of all character sets on the
  LQ disk by typing DIR *.SET at the DOS prompt '>'.  A printout
  of current sets is given in Section 9.

 If the 'C' option is followed by a file name in quotes, the
  character set having this name is loaded to the indicated set
  number.  For example,
            LQ C2'PRETTY'
  would load the character set PRETTY.SET as set number two
  (without switching to it).  The 'SET' suffix is the default; you
  should stick with this naming convention to maintain
  compatibility with the character editor EDCHAR.  You can
  simultaneously load a set and switch to it by using 'C' in both
  contexts; e.g.,
            LQ C2'PRETTY' C2.
  You can load all four sets in one line:
            LQ C1'FIRST' C2'SECOND' ...
  You can also use path names in the file specification:
            LQ C1'/MYDIR/FIRST'

D
  Loads LQ in draft mode.  This is useful if you want to use LQ's
  spooler without switching to the LQ mode.  You can always toggle
  the two modes with LQ's pop-up window.

F
  If you have a file named MYFILE, the command
            LQ F'MYFILE'
  will print MYFILE without locking LQ into memory.  This is an
  important option if your computer doesn't have enough memory to
  keep LQ resident, or if most of your printing is in draft mode.
  The file to be printed should be a standard text file, possibly
  containing some of the control sequences described in Section 3.
  You can send LQ's output to a file rather than to the printer by
  giving a second file name.  For example,
            LQ F'MYFILE','MYFILE2'
  will send the output to MYFILE2.  See Section 4 for details on
  the file mode.

K
  This lets you override the default key combination used to bring
  up the Control Window and assign a new pair of keys.  Use the
  following values:

     3 - Right Shift + Left Shift,
     5 - Right Shift + Ctrl,
     9 - Right Shift + Alt,
     6 - Left Shift + Ctrl,
    10 - Left Shift + Alt,
    12 - Ctrl + Alt,
     N - Disable window.
LQ parameters                                                   18


  For example, LQ K12 specifies the <Ctrl> <Alt> combination, and
  LQ KN disables the window.

L
  Sets the number of lines printed on a standard 11" page.  The
  default is 66; LQ L70 changes this to 70.  The number entered
  must be from 1 to 95.  Spacing between lines is micro-adjusted
  using the smallest line advance supported by your printer
  (1/216" or 1/144").

M
  Sets one or more of the following modes:
   E: emphasized printing,
   L: large (triple-high) printing,
   N: narrow (elite) printing,
   P: proportional spacing,
   W: double-wide printing.
  For example, LQ MEP could be used to turn on emphasized
  proportional printing.  Modes omitted default to the opposite
  state.

Q
  Suppresses the display of LQ's 'welcome' screen and begins
  execution immediately.  This is useful in batch files; for
  example, the commands
    LQ F'MYFILE' C1'SANSSER' Q
    LQ F'YOURFILE' C1'HELV' Q
  could be executed without the need for an operator to press a
  key to continue.

R
  The command
    LQ R
  removes LQ from RAM and returns the memory previously used to
  your system.  This option can be used only if LQ was the last
  'memory-resident' utility loaded.

S
  Sets the space per line in units of the smallest possible line
  advance.  For example, on an Epson (which advances in multiples
  of 1/216"), the command LQ S30 would set the distance between
  the tops of successive lines to 30/216".  The 'L' parameter
  generally offers an easier way of accomplishing the same
  objective.

W
  Wait at page breaks.  Use this for printing with single-sheet
  paper.  Each time the form feed character  (ASCII code 12) is
  encountered in a printout you will be prompted to
    Press <Enter> for next page:
  (In the file mode you can also press <Esc> to abort the
  printout.)

#
  Specify printer number (0,1 or 2) to be used by LQ.  If you have
LQ parameters                                                   19

  just one printer don't use this parameter; the proper value (0)
  is set by default.
7. Creating or modifying a configuration file.

    If your printer is compatible with an Epson or another printer
for which a configuration file (with suffix PAR) exists on the LQ
disk, just follow the directions in Section 2 for letting LQ know
what you have.  If neither the built-in configuration nor any of
the PAR alternatives work, you will have to write your own
configuration file.  If you have problems, send us a copy of the
control code section of your printer manual and we will try to
write the file for you.  For LQ to work properly, your printer
must support

  1. a graphics mode in which 8 pins of the print head can be
     individually controlled, and

  2. a minimum line advance of either 1/216" or 1/144".

In addition, the graphics mode must be entered with a control
sequence telling the printer how much subsequent data will be in
graphics mode.  A prominent counterexample is the Okidata 92,
which

  1. controls only 7 pins in graphics mode, and

  2. uses one control sequence to turn graphics on and another to
     turn it off.

Later model Okidata printers and those equipped with the
Plug'N'Play ROM module do support LQ.

    A configuration file is a text file named with a suffix of PAR
which contains lines typically starting with a symbol indicating a
definition category, followed by a letter specifying the function
to be set, then the '=' character, then a word or sequence of
characters and numbers giving the definition itself.  For example,
    %A=27,'E'
indicates that emphasized print will be turned on with the <ESC>
'E' sequence (that normally used by the Epson).  A control
sequence is a list of codes and/or characters separated by commas;
characters are put within quotes (one pair of single quotes per
character) and codes are given as decimal numbers.  The definition
    %A=27,69
is equivalent to that above since 69 is the ASCII code for 'E'.
(See Appendix B for a listing of ASCII codes.)  The leading symbol
indicates one of the following categories:
    % - a control sequence for a mode definition,
    & - a control sequence to ignore,
    $ - one of the words TRUE, FALSE,
    # - a decimal number.
A line starting with any other symbol is treated as a comment.

LQ parameters                                                   20

    While a complete listing of LQ parameters is given below,
there are only a few that you will need to change to create a
customized PAR file for a new printer.  These are:
  %N, %O, %P, %Q, %R
  $A, $B, $C
  #A, #B
To install LQ with your new printer XYZ we recommend the following
procedure:

  COPY EPSON.PAR XYZ.PAR

  Edit the XYZ.PAR file (using EDLIN or another editor which can
  handle standard ASCII files): modify the 10 parameters listed
  above to describe your printer's functions.

  Run LQINST as described in Section 2.

Remember that LQ will make your printer appear to a word processor
as an Epson MX 80 (or IBM Graphics Printer), so perform the
necessary installation on your word processor as well.

    Two values have special significance in a control sequence.
The number 0 will match 0 or '0' (the character whose ASCII code
is 48), and the number 255 will match anything else.  For an
illustration, see the description of the &A parameter in the
EPSON.PAR listing below.

    Here is the information LQ needs (any one of these omitted
defaults to the Epson value):

       % parameters.

  %A - control sequence for turning on emphasized print,

  %B - sequence for turning off emphasized print,

  %C - sequence for turning on double-strike print,

  %D - sequence for turning off double-strike print,

  %E - sequence for turning on italics,

  %F - sequence for turning off italics,

  %G - sequence for turning on double-wide print,

  %H - sequence for turning off double-wide,

  %I - sequence for turning on underline mode,

  %J - sequence for turning off underline mode,

  %K - sequence for turning on superscript,

  %L - sequence for turning on subscript,

LQ parameters                                                   21

  %M - sequence for turning off superscript/subscript,

  %N - prefix for turning on high-resolution graphics. For example,
       the Epson MX 80 manual describes its high-resolution mode
       as follows: <ESC> L  Sets dot graphics mode to 960 dots per
       8" line.
                Format: <ESC> 'L' N1 N2, N1 and N2 determine
                line length.  Line length = N1 + 256*N2,
                1 <= N1 <= 255, 1 <= N2 <= 255
       Thus you would enter the prefix in your configuration file
       as %N=27,'L' or %N=27,76.  (You would also set the number
       of graphics bytes to 2 with #A=2, and non-ASCII (binary)
       number format with $B=FALSE.  See below.)  If you have
       several graphics densities to choose from, pick the one
       closest to 960 dots per 8" line (120 dots per inch).

  %O - In a similar fashion, %O gives the prefix used to set line
       feeds in units of the smallest possible increment.  Again,
       here is the appropriate material from the Epson manual:
       <ESC> 3  Sets line spacing to N/216".  Format:
                <ESC> '3' N, 1 <= N <= 255
       You would enter %O=27,'3' (and set the number of line feed
       bytes with #B=1).

  %P - The control sequence used to put your printer in
       'unidirection' mode.  Most dot matrix printers print in
       both directions to speed up output, but the resulting
       characters are apt to vary in alignment.

  %Q - The sequence of characters you would like sent to your
       printer when LQ is disabled from the Control Window.  This
       should include an appropriate line feed setting and a
       return to bidirectional printing.  You can also reset your
       printer by turning its power off and on.

  %R - The sequence of characters you would like sent at the start
       of each line printed by LQ.  Epson-compatible printers
       don't need this parameter, but it can be very useful for
       other printer types.  For example, the C. Itoh doesn't have
       a separate 'high-resolution' graphics mode; graphics
       printing functions in the last character pitch (pica,
       elite, compressed,...) set.  The most appropriate pitch is
       compressed; %R=27,'Q' sets this at the start of each line.

       & parameters.

  &A - A sequence of characters to ignore (filter) from a
       printout.  Word processors often send initialization
       sequences which might appear as 'garbage' when printed by
       LQ.  The '&' parameters have been set to take care of any
       problems that could arise with the Epson MX / IBM Graphics
       Printer.

  &B, ... ,&L -
       Additional sequences to ignore.

LQ parameters                                                   22

       $ parameters.

  $A - You control 8 pins on the print head in graphics mode.  The
       pins correspond to the numbers 1,2,4,8,16,32,64,128; for
       example, to fire the two pins corresponding to the numbers
       2 and 16, the code 18 is sent to the printer.  If the
       highest pin corresponds to 1 and the lowest to 128, set
       $A=TRUE; if the order is reversed, set A$=FALSE.

  $B - There are two ways various printers accept numeric values:
       ASCII and binary.  To indicate to an Epson printer that 300
       graphics positions are about to be printed, the prefix
        <ESC>,'L',44,1
       is sent.  The numbers 44 and 1 are combined as 44 + 256*1
       to obtain the number 300; this is the binary format.  On
       many other brands of printers the number 300 would be sent
       as '3','0','0' or '0','3','0','0' in ASCII format.  Set
       $B=TRUE for ASCII or $B=FALSE for binary.

  $C - Set $C=TRUE if the minimum line space your printer will
       accept is 1/216"; if this value is 1/144", set $C=FALSE.

       # parameters.

  #A - The number of bytes after the graphics prefix (specified
       with %N) used to set the number of bytes expected by the
       printer.  For example, to print 300 bytes in high-
       resolution graphics you first send the Epson the sequence
       <ESC>,'L',44,1; since the prefix takes up two of these four
       bytes, the remaining two determine the setting #A=2.  The
       same task on a C. Itoh requires sending
       <ESC>,'S','0','3','0', '0', so you would set #A=4.

  #B - The number of bytes after the line feed prefix (specified
       with %O) to determine the space advanced by a line feed.
       (See #A.)

    Any setting omitted in a configuration file defaults to the
corresponding Epson value; see the EPSON.PAR listing below.

Creating the configuration file.

    Now that you know what to put in your configuration file, how
do you actually create one?  Any screen or line editor will do;
you will probably want to use your accustomed word processor.  If
you have no other alternative, you can always use the EDLINE line
editor which comes with DOS.  Just make sure that you create a
standard ASCII file, not a file in a special non-ASCII format used
internally by your program.  To see if you can make such a file,
try writing a 2-line test file and store it under the name
TESTFILE.  Then (at the DOS prompt '>') enter TYPE TESTFILE; if
the lines look right on your screen, you are probably in luck.
Check your word processor index under ASCII for details.

    If you have an unusual printer and succeed in creating a new
configuration file for it, please send us a listing of your file.
LQ parameters                                                   23

In return, if your configuration is significantly different from
those we already have on record we will send you a free LQ update.

The EPSON.PAR configuration file.

    If you are using an Epson printer or close compatible you
should never need a configuration file; all needed parameters are
already set by default.  However, if you are creating a new
configuration file for a different printer it is instructive to
look at the EPSON.PAR file which lists the Epson parameters; the
form f the file may be helpful, and you should know what the
defaults are in case you omit a parameter line.  Here are the
Epson values:

  %A=27,'E'

  %B=27,'F'
  {double-strike on:}
  %C=27,'G'

    {the 255 code will match any 1-byte value except for 0 and
     '0'=48.  Likewise, 0 matches 0 or '0'=48.  This means you can
     turn off underlining in a document with the sequence
     <ESC> '-' '0', which is much easier to insert than
     <ESC> '-' 0.}

  %J=27,'-',0

8. Tips for better printouts.

    LQ obtains its high quality print by making three passes over
each line, placing dots at very precise positions.  Any 'play' in
the paper can disrupt this precision and blur a line of print.  We
recommend that you keep the alignment precise by using friction
feed for single-sheet printing, or by making certain that there is
uniform tension on the paper when using pin-feed paper for longer
printouts.

    As previously mentioned, the first line of print is something
of a special case.  When your printer is first turned on there is
not apt to be sufficient tension on the paper to obtain the needed
precision on the first line.  This problem is solved by advancing
the paper a negligible distance; this is done automatically when
you use the F option for printing files or when LQ is loaded in
the resident mode (if the printer's power is on).  In other cases
you can use the Control Window to advance the paper by pressing
the 'A' key.  You can also begin a document with a blank line or
with <Esc> <Esc> B (see Section 5).

    Proportional spacing can improve the appearance of a document,
but this mode must be used with caution.  Since extra 'white
space' between characters is removed and since the amount of such
space varies considerably (e.g. compare the characters 'i' and
'w'), tables of data can be distorted.  For example, if the two
lines
    iiii            xxxx
    wwww            yyyy
were printed with proportional spacing, the 'yyyy' would be
further left than 'xxxx'.  One way to avoid this problem is to
turn proportional spacing off (with <ESC> <ESC> 'Q') just before
Character sets                                                  25

the table and back on (<ESC> <ESC> 'P') at the end of the table.
With PC-Write you can use an 'align font' to preserve column
alignment with proportional spacing; see the file LQPCWRIT.DOC for
details.

    Most LQ modes are enhancements of familiar print styles, so
your word processor should not require special consideration.
However, triple-high characters will definitely come as a surprise
to any program which thinks it is counting 1/6" lines; you will
use up a sheet of paper three times faster than your word
processor expects.  To fix this, you can change the number of
lines per page in your word processor, or take charge yourself in
other ways.  One compromise has been made to keep margins
consistent:  if the string
   '       This is a test.'
(7 spaces preceding 'This') is printed in 'large character' mode,
the leading spaces are printed as normal characters.  This lets
you set the margin to a fixed value in your word processor rather
han worrying about whether the margin is in terms of large or
regular spaces.


9. Character sets available in LQ.

     To see a list of all character sets on the LQ disk, type DIR
*.SET.  To obtain a printed copy of all character sets type
PRINSETS.

    The default sets installed in LQ are

    1 - COURIER.SET
    2 - COURITAL.SET
    3 - HELV.SET
    4 - PALATINO.SET

The second set is an italicized version of the first and will be
used automatically when you tell your word processor to use
italics.  The other such pairs of sets are
    HELV.SET            HELVITAL.SET
    MAIN.SET            MAINITAL.SET
    ROMAN.SET           ROMANITA.SET
    SANSSER.SET         SANSITAL.SET
    SANSSER2.SET        SANS2ITA.SET

Other sets currently included do not have italicized companions.

    You can change the fonts which are loaded automatically as
part of LQ with the LQINST program.  You can also create or change
fonts with the EDCHAR program.


10. Editing character sets: the EDCHAR program.

    Sooner or later you will probably want to modify one of the
character sets provided with LQ, or make a new set from scratch.
For example, you may need a couple of special technical symbols
Editing character sets                                          26

occasionally, or you may fall in love with an altogether new font.
The EDCHAR program included on the LQ disk offers a convenient way
to edit characters in the format expected by LQ.  The basic
sequence is to run the program, specify the character set you want
to edit (which may be an existing set or a new one), edit one or
more characters corresponding to the ASCII codes 32-127, then save
the revised (or created) set.  EDCHAR also lets you move
characters from one set to another easily.

    To get started simply insert the LQ disk and type EDCHAR.  If
you want to edit an existing set, you will want to load it now; if
you are creating a new set, you can skip this step.  Press 'L' to
get the following L(oad) submenu:

  1. Load main character set.
  2. Load auxiliary character set.
  3. Return to Character Editor.

If you choose one of the first two options you are shown a list of
all character sets in the current directory, and you are given a
chance to select a set or to change the directory from which you
will select a set.  For example, if you enter '\MYDIR\', the path
will be changed to the indicated directory and all character sets
(files ending in '.SET') in this new directory will be listed.
Similarly, if the font you want is in the main directory of drive
B you would simply enter 'B:'.  You can browse through all your
directories in this fashion, and when you find the one containing
the set you want just type the set's name.  The set will be loaded
into memory as the main or auxiliary set depending on your
previous menu selection.  The main difference between these two
categories is that the main set can be altered but the auxiliary
set cannot.  The only reason to use an auxiliary set at all is to
transfer characters to the main set.

    Let's assume that you have loaded a main and/or auxiliary
character set if necessary and that you are ready to edit a
character.  Press 'G' to obtain the G(et) submenu:

  1. Get character from current set.
  2. Get character from auxiliary set.
  3. Edit new character.
  4. Return to Character Editor.

If you choose one of options 1 - 3, you will be prompted to enter
the ASCII code of the character or the character (preceded by a
single quote) itself.  For example, you can specify the letter 'A'
by entering the code 65 or by entering 'A.  If you selected option
1 or 2, you will see the existing character from the appropriate
set ready for editing; if you choose option 3 you will see a clear
edit window.  (See Figure 1 for a typical display.)  A character
is edited as a 24 X 10 matrix of dots, each of which is turned on
or off.  You can use the arrow keys along with the Home, End, Pg
Up and Pg Dn keys to position the cursor.  Pressing the space bar
toggles the state of the dot under the cursor.  At any time you
can also select any of the menu options listed on the right of the
screen.

                        Figure 1

    When the character has been edited to your satisfaction, you
can put it into the main character set with the P(ut) option.  You
will be given a chance to change the code under which the
character will be stored, but more than likely you will use the
default: the code you used with the G(et) command.

    There are three levels of storage used in EDCHAR.  The
ultimate (and only safe) storage site is your disk, and only
complete sets, not individual characters, are saved as files on
disk.  There are also the main and/or auxiliary character sets in
your computer's volatile memory; since the power may flicker at
any time, you should backup a set you are editing on a regular
asis.  Finally, there is the individual character being edited:
modifying this character affects neither the set in memory nor the
set on disk.  Only when you P(ut) the character to a set is the
set in memory changed, and only when you S(ave) the set in memory
is the set on disk changed.

    When editing a character, you have at your disposal the
following options:

  B)ackup character - pressing 'B'makes a copy in memory of the
    character definition currently displayed.

  C)lear character - pressing 'C' blanks the character matrix, but
    doesn't affect the corresponding character in the set being
    edited.  (Remember, only the P(ut) command changes that.)
Editing character sets                                          28


  G)et character - the first step in editing a character.  You are
    shown the following menu:
    1. Get character from current set.
    2. Get character from auxiliary set. 3. Edit new character. 4.
    Return to Character Editor. In order to get a character from a
    set (options 1 and 2) you must first L)oad the set.

  M)iddle - lets you center a single character or an entire set.
    You are shown the following menu:
      1. Center character.
      2. Center entire set.
      3. Return to Character Editor.
    Selecting the first option centers the character definition on
    the screen, while choosing the second centers all of the
    character definitions in the main character set.  If
    characters are not centered then spacing within words can
    appear irregular; it is always a good idea to center the
    entire set when you are finished editing it.

  P)ut character - replaces corresponding character in the main
    set with that shown on the screen.  If you don't press 'P'
    your editing will not change the character set.  You are asked
    whether the character on the screen should be saved under the
    code under which it was loaded or under a different code.  For
    example, you could load a 'P', modify it a little, then save
    it as the character 'R'.

  Q)uit prompts you to make certain you're serious, then returns
    to DOS.

  R)estore character is the reverse of backup - the last character
    definition backed up with the 'B' option replaces that being
    displayed.

  Backup and restore let you experiment with a character
    definition without altering a set on disk.

  S)ave character set - pressing 'S' lets you save the set being
    edited under the name used for loading the set, or under any
    other name.  You are prompted to enter the name of the set or
    the path for saving.  You can overwrite the previous version
    simply by pressing return, or you can create a separate second
    version by changing the path or name.  You will want to use
    the S(ave) option often since it provides cheap insurance
    against power fluctuation and other perils to your data.

  T)able for PC-Write - this option allows you to create a width
    table for proportional spacing in PC-Write.  See the file
    LQPCWRIT.DOC for details.

  W)rite character lets you see how your character looks on paper
    if you have an Epson-compatible printer attached.  You will be
    prompted to turn on your printer, then the character being
    displayed will be printed in LQ mode.  (LQ should not be
    installed in memory if you use this option.)  Note that while
Additional programs                                             29

    LQ works with printers which are not Epson-compatible (through
    the use of PAR configuration files), EDCHAR does not.  This
    simply means that if you want to see your new characters on
    paper, you may have to wait until you exit EDCHAR and run LQ.

Tips on editing character sets.

    Make certain that you use the same 'base lines' for all the
characters in a given set, so that the characters will line up
properly when printed.  The following should be aligned:
  the base of characters without descenders,
  the top of lower case letters such as 'a' and 'c',
  the top of upper case letters.

    If you want to create a new font, you may want to work from an
existing font.  For example, you might reuse the punctuation
symbols but change the letters and numbers.  To do this, copy (at
the DOS prompt) the set to be edited to a new name:
 A> COPY OLD.SET NEW.SET.
Now you can run EDCHAR and edit the new set without risking your
old set.  The same thing can be accomplished from within EDCHAR by
loading a set, editing it, then saving it to a different name, but
you must be sure to enter the new name or your old set will be
lost.


11. Additional programs.

    There are a few additional programs and files on the LQ disk
which can enhance your use of the package.  Included are
LETHEAD.COM, LETHEAD.DOC, BIGPRINT.COM, PRINTBIN.EXE and
LQPCWRIT.DOC.  Following is a description of each:

LETHEAD - the LQ letterhead editor.

     LETHEAD is a graphics editor which works in conjunction with
LQ to produce high-resolution letterheads consisting of 1" x 1"
pictures and up to four lines of accompanying text.  Each picture
(23040 dot positions) is stored in the format of an LQ character
set, although the picture segments don't look like characters.
LETHEAD lets you
  edit a picture
  save a picture
  load a picture
  create a data file to be printed with the picture serving as one
  of LQ's character sets (the letterhead).  The final product can
  be printed with a one-line batch file.

    The basic idea behind printing pictures is that all LQ
characters are arbitrary graphics shapes anyway, so a block of
them can be combined to make a larger image.  The only problem is
the space that is normally inserted between characters and between
lines.  By preceding a sequence of characters with the control
code '<Esc> <Esc> C', no space will be inserted; '<Esc> <Esc> D'
returns LQ to the usual mode.  If the graphics mode is active at
the end of a line then the next line will start exactly where the
Additional programs                                             30

last line left off regardless of the current line space setting.
LETHEAD automatically inserts the proper control sequences when
you use it to create a letterhead.  Typing LQDEMO will produce a
printout which includes a spiral pattern; look at the file
DEMODATA.1 to see the data which produces this picture.

    For complete instructions on using LETHEAD you will need to
print the file LETHEAD.DOC from the LQ disk by typing
  PRINTMAN LETHEAD.DOC.
To view the manual on the screen, enter
  PRINTMAN/S LETHEAD.DOC.


BIGPRINT: a banner printer.

    BIGPRINT.COM is a program which will let you print banners in
any LQ font.  After you type BIGPRINT you will be prompted:

  This program lets you print posters using any of the LQ
  character sets.

  Name of character set? (Default = ROMAN.SET)

Enter the name of the LQ font you wish to use, or just press
<Enter> to accept the default of Roman.  Next you are asked

  Is your printer Epson-compatible?

Type Y or N as appropriate, then press <Enter>.  Finally you are
asked to

  Enter string:

At this point enter the text you wish to print; the string will be
printed lengthwise on your paper with characters about 5" high
(centered on 8.5" wide paper).


Using the DOS PRINT utility to spool LQ files to disk.

    Print spoolers offer a natural way to relieve perhaps the most
prominent bottleneck in your computer system - the slow speed of
your printer.  By printing in the background while other
processing tasks continue you are free to continue using your
computer rather than sitting idly by.  LQ has a built-in spooler
which is customized for the graphics printing that LQ does, but it
does take up some of your valuable RAM.  An alternative is to make
use of the PRINT.COM utility which comes free with your DOS - this
program lets you keep the queue of characters waiting to be
printed on disk rather than in RAM.  If you have a hard disk you
may have millions of characters of free space, so this presents an
attractive alternative.  However a few qualifications are in
order.

    If you plan to print documents in LQ mode using PRINT.COM, LQ
must first process the file, and this involves a 40-fold expansion
Additional programs                                             31

in its size.  For example if MYFILE is 1000 characters long, then
the file MYFILE.OUT created by entering
  LQ F'MYFILE','MYFILE.OUT'
(see Section xx for a description of the F parameter) will be
about 40,000 characters long.  The new output file contains lots
of control characters which will prompt PRINT.COM to take some
inappropriate action (such as converting tab characters to
spaces); PRINT was designed for printing program listings and
such, not arbitrary binary files.  You must create a modified
version of PRINT to deal with the latter.  To this end the program
PRINTBIN.EXE has been included on the LQ disk.  You will need this
program and the DOS PRINT.COM program available at the same time;
after you enter PRINTBIN you will see the following screen (with
your entries indicated in boldface):


  PrintBin (c) Copyright 1988 by Mark Harris.
  All rights reserved.  6/1/88

  This program makes a copy of the DOS PRINT.COM utility (from
  your system disk) and modifies it to let it print binary files.
  It also suppresses the form feed which PRINT normally adds to
  the end of a file.  The new program will be called BPRINT.COM.

  Type location of PRINT.COM or press <Enter> if in default
  drive/directory: (e.g. A: or C:MYDIR1MYDIR2)
  \DOS

  Type location for BPRINT.COM or press <Enter> for default
  drive/directory:
  B:

    In this case the PRINT.COM program was in the subdirectory
\DOS on the default drive and the new program BPRINT.COM is to be
put on the disk in drive B.  Substitute your own paths and/or
drives.

    The original PRINT.COM is unchanged but now you have a new
program BPRINT.COM for printing binary files.  Consult your DOS
manual for instructions on its use.  (Treat it just as you would
PRINT.COM.)

    There are several steps in printing files in the manner
described above; here is a summary of the process:

1. You enter text in your word processor to create FILE1.
2. You output from word processor to file instead of printer to
   create FILE2.
3. LQ F'FILE2','FILE3'
4. BPRINT FILE3
5. Now use your computer will printing continues in the
   background.  Delete FILE2 and FILE3 when printing is finished.

Using LQ with PC-Write.

    LQ works well with most word processors, but especially well
with PC-Write.  Any LQ feature can be exploited easily from PC-
Write; in particular, microjustification and proportional spacing
are fully supported.  To get an idea of what this can do for the
appearance of your documents type LQDEMO; the printout you'll get
was formatted with PC-Write.

    For details on the LQ/PC-Write combination, see the file
LQPCWRIT.DOC.  You can obtain a printout by entering
  PRINTMAN LQPCWRIT.DOC.
To view the manual on the screen, enter
  PRINTMAN/S LQPCWRIT.DOC.


Appendix A. About 'Shareware'.

    'Shareware' is a relatively new means of software distribution
with several advantages to you the consumer.  The complete package
including this instruction manual is contained on a single
diskette which may be freely copied and distributed.  Word of
mouth provides a more accurate and less expensive way of making a
product known than magazine advertisements, and the savings keep
LQ's cost down.

    Shareware does not mean 'public domain'.  Distribution is
permitted only if the package stays intact; all files should be
passed on in unmodified form.

    You can obtain the current LQ disk from Granny's Old-Fashioned
Software for $10 or a registered package for $35.  Registration
provides the following benefits:

  1. A current version of LQ including printed manual,
  2. a mail-in card for a future version of LQ,
  3. a $10 commission each time someone registers from one of
     your copies,
  4. telephone support for your technical questions.

To register, phone (with MC or VISA) [phone] or
mail payment to:

          Granny's Old-Fashioned Software

          Boone, NC 28607

North Carolina residents please add 4.5%.  Foreign orders please
add $3.00 for shipping.

Please include the registration number from the upper right of
LQ's initial display so that we can reimburse the person from whom
