Introduction ---------------------------------------------------------
PrintGL is a shareware pen plotter emulator for IBM/DOS systems. It
prints or displays HP-GL (Hewlett-Packard Graphics Language - 7475,
17440 subset) plotfiles on most PC graphics devices. HP-GL is widely
supported by CAD, drawing, plotting, and other graphics programs
including AutoCAD, Microstation, Generic CADD, MathCAD, Schema,
OrCAD, and SAS. PrintGL will print on Epson and IBM 9 pin printers,
Epson, Fujitsu, IBM, NEC, and Toshiba 24 pin printers, HP LaserJet,
DeskJet, color DeskJet, PaintJet, QuietJet, and plotters, IBM
ExecJet, Quietwriter 2 and 3, LaserPrinter, and plotters, Canon LBP,
BJ, and BJC printers, Kodak Color 4, and PostScript printers. It
will also display plots with a CGA, EGA, VGA, enhanced VGA, or HGC,
and output a ZSoft .PCX or GEM .IMG bit map file.
Even if your graphics program supports your printer, you will
probably find that PrintGL is faster, gives better print quality,
and/or gives more formatting flexibility. PrintGL uses the best
graphics modes available for each printer that it supports and uses
transfer data compression to improve print speed on many printers.
And it gives options such as orientation, magnification, position,
and pen width, color, and shading. If you need printed graphics
output from personal software, you can output HP-GL and use PrintGL
to do the printing. This gives immediate support to a wide range of
printers. And it lets you use the HP 17440 command set while still
supporting lower function plotters.
PrintGL interprets all of the HP 7475 and 7440/17440 (ColorPro with
GEC) command set that is applicable to plotfiles except for
character set 8 (Katakana). None of the digitize, output, or device
control commands (except plotter on and off) are supported as these
are only used with direct control of a plotter. And the error mask
command is not supported. In addition to the HP 7475 and 7440/17440
commands, PrintGL handles paper feed, extra space, and label origin
commands and proportional fonts from the HP 7550 command set.
PrintGL can be run from the DOS command line (and .BAT files) or
from PrintGL Menu Interface (PMI). PMI is a menu driven program that
lets you choose PrintGL options, select a list of plotfiles, and run
PrintGL. This simplifies the selection of PrintGL's many options and
lets you run multiple plotfiles without intervention. PMI lets you
save three configurations, so after initial setup you can use
PrintGL with minimal effort.
This program is produced by a member of the Association of Shareware
Professionals (ASP). ASP wants to make sure that the shareware
principle works for you. If you are unable to resolve a
shareware-related problem with an ASP member by contacting the
member directly, ASP may be able to help. The ASP Ombudsman can help
you resolve a dispute or problem with an ASP member, but does not
provide technical support for members' products. Please write to the
ASP Ombudsman at 545 Grover Road, Muskegon, MI 49442 or send a
CompuServe message via CompuServe Mail to ASP Ombudsman 70007,3536.

Installation ---------------------------------------------------------
The PrintGL package includes these files:
PRINTGL.EXE program
PRINTGL.DOC documentation
CHARSET.PLT HP-GL character set plotfile
PMI.EXE menu interface program
SAMPLE.PLT sample plotfile
README.* quick information
To install PrintGL copy the distribution files to your working disk
or directory.
PRINTGL.EXE is a stand alone executable file. There are no extra
printer driver files or overlays.
PRINTGL.DOC is this manual. You can print it with "COPY PRINTGL.DOC
PRN". The HP-GL character sets may be printed with the command
PRINTGL CHARSET.PLT /M1 /AO0,0 and a /F option specific to your
printer, and inserted in the manual.
PMI.EXE is the executable file for PrintGL Menu Interface. PMI needs
to be able to find itself (PMI.EXE) and PRINTGL.EXE, so both of
these files should be in a directory that is in your DOS PATH. If
you prefer, you can set the environment variable PRINTGLP to be a
path that tells PMI where to find itself and PRINTGL.EXE. If you
have PRINTGLP defined, PMI ignores the PATH value.
SAMPLE.PLT is a sample plotfile to help you try out PrintGL.
The README.* files are not needed to run PrintGL, but they must
accompany the rest of the files if you distribute the package.
p-6
Operation ------------------------------------------------------------
PrintGL reads a plotfile, does arc, character, fill, etc. to line
conversion, stores the data in a coordinate list, and if needed,
puts the list on disk. It then reorients the data and determines the
plot size. Next the data is resized and relocated. For vector output
formats (HP-GL, PostScript) data is output from here. For bit mapped
devices (most printers, displays, bit maps) the coordinate list is
rasterized and output in swaths. You are likely to see the printer
print a swath and stop while PrintGL is processing the next swath.
When you display a plot, press Esc to return to the DOS text screen,
or any of the four cursor movement keys to scroll across the plot.
Press S to cycle between full, half (the default), quarter, and
eighth page scrolling. Ctrl-Break stops PrintGL at the next break
point. Ctrl-Break is ignored when PrintGL is waiting for user input.
PrintGL works within a printer's current margins and starts at the
current vertical print position. If you decline the form feed
suboption of the /L option then PrintGL leaves the printer at the
start of the line directly below the plot. All printing is done in
printer lines that cover the full height of the printhead.
PrintGL will not automatically change a printer's operating mode. On
multimode printers, the right operating mode must be set before
running PrintGL or with the /J option.
Internally PrintGL uses two byte coordinates on a 1016 dots/inch
grid. This allows for plots with coordinates of over 30 inches - far
larger than an HP 7475 can handle. However, if you are using PrintGL
to emulate a large plotter, you may overflow the internal coordinate
system. This condition is not checked, and it will cause garbage
output. You can change the internal resolution to 508 dots per inch
(giving 60 inch maximum plot sizes) with the /R option (/R508). This
only helps store the original plot internally. The next step in
PrintGL converts these coordinates to the requested size in the
resolution of the output device, and these coordinates must also fit
in the two byte coordinate list.
How To Get HP-GL Plotfiles From Your Graphics Software ---------------
To use PrintGL, you must be able to output HP-GL files from your
graphics application. Most CAD, drawing, and graphing software lets
you do this. Just tell the application to output your picture to a
plotter. In either the configuration process or the output process,
you will need to specify that: you have an HP 7475 or HP 7440/17440
plotter; and that you want the output to go to a file instead of a
COM port (some programs name the file automatically and some ask you
for a name). Once you have the file, you can print it with PrintGL,
either from a DOS shell or after exiting the application.
p-7
Messages -------------------------------------------------------------
PrintGL displays a number of messages to keep you informed of what
it is doing. The output looks like this.
Reading SAMPLE.PLT
Plotfile has 1 page(s) Processing page 1 2283 data records
Overall magnification 0.9964
Print window Horizontal 0.00 7.54 Vertical 0.00 10.14
Plot area Horizontal 0.42 7.13 Vertical 0.61 9.54
Output format /FN 120x72 dots/inch (HxV)
Writing to device LPT3
The first line is the plotfile that is currently being processed.
The second line tells how many pages are in the plotfile, which page
is being processed, and the number of data points in that page. The
number of data points is roughly equivalent to the number of pen
moves and is shown to give you an indication of the plot's
complexity.
The overall magnification is either the magnification that you
specified with the /M option or the effective magnification after
fitting to the print window with /MF. The print window line gives
the horizontal and vertical coordinates of the print window, always
starting at 0,0 and in inches. The plot area gives the horizontal
and vertical coordinates of a box that just covers the plotted data.
This uses the same coordinate system as the print window, so you can
tell where the plot is relative to the print window.
The output format and resolution are given and then the output
device is noted (except for screen plots). If three plane color is
being used, the word "color" is displayed. If you have a black only
printer, but the output format allows color (this is common with 9
and 24 pin printers), using color will triple the PrintGL run time
with no improvement in print quality.
During processing, PrintGL informs you when it is processing and
writing data, and you can watch the progress from 0% to 100%, along
with the elapsed time.
p-8
Syntax ---------------------------------------------------------------
The calling syntax of PrintGL is:
PRINTGL plotfile /option1 /option2 ...
Spaces between parameters are not required. The plotfile may be
specified with the /P option if it is inconvenient to make it the
first parameter.
If a given option is entered more than once, only the last entry is
used. And if an option is invalid (but not incorrect), it is
ignored. This lets you set up a batch file with your preferred
options but override them as desired. For example, create PHP.BAT
with the line:
PRINTGL /FL /M1 /P %1 %2 %3 %4 %5 %6 %7 %8 %9
Then PHP can be called just like PRINTGL but it defaults to HP
LaserJet format with magnification 1.
The DOS environment variable PRINTGL is examined by PrintGL and if
it is nonblank then it is put in front of the command line
parameters. If you put "SET PRINTGL=/FL/M1" in your AUTOEXEC.BAT
then PrintGL will default to LaserJet format with magnification 1.
This is ignored when running under PrintGL Menu Interface.
If you do not enter any parameters or if any parameter is incorrect,
PrintGL displays its option reminder screen.
Below, [ and ] enclose optional suboptions and | separates mutually
exclusive suboptions. The options and suboptions may be in any order
except that multiple numeric suboptions are ordered and numeric
suboptions must follow character suboptions where the characters may
be digits. "c" refers to a suboption character, "x" and "y" to
suboption numbers, "i" and "j" to suboption integers, "b" to a
suboption byte, and "f" to a DOS file or device name.
For numbers (x, y), a decimal point is allowed but is not required,
and scientific notation is not allowed. "-" is allowed but not "+".
For integer input (i, j), only base ten integers from -32768 to
32767 are allowed. "+" is not allowed. A byte (b) must be a base ten
integer from 0 to 255 or a hexadecimal number prefixed with $ from
$00 to $FF. Further range checking is done for most options to flag
unreasonable input. If an option has multiple numeric suboptions,
these may be separated with commas or blanks.
********************************************************************
It is very important to choose the right output format (/F option).
It is likely that the default output format will work on your
printer, but it is equally likely that it will not produce optimal
results. Please look carefully at the entire list of output formats
before choosing one, and do not assume that because a format works
that it is the best one to use.
********************************************************************
p-9
Overview of Options --------------------------------------------------
PrintGL's options fall into several categories. The first is input
and output choices. The input is chosen with /P, the plotfile, and
/N, the page number. Output options are /F, the output format
(printer model), and /D, the destination port, device, or file.
The second category is the page layout, which is mostly contained in
the /L option. This includes the size and location of the print
window (which defines the hard clip limits of the plot), and the
option to box the window, send a form feed, reverse the image color,
and use opaque lines. And tiling is controlled with /B.
The third category defines how the plot looks within the print
window. /M, the magnification, sets the size of the plot. /A
determines the location of the plot within the print window. /O sets
the origin and orientation, and is used to rotate or mirror the
plot. /I sets the initial scaling points as if you had set them from
the front panel of the plotter.
The fourth category defines the pens, /W for the width, /C for the
color, and /S for the shade.
And the last category determines how PrintGL processes the plot.
This includes the temporary file /T, the default and minimum chord
angle /Z, the plotter Y/D switch position /Y, the internal
resolution /R, user interface options /X, and /J and /K let you set
up and reset the printer for special situations.
/A - Location Option -------------------------------------------------
/A[O][x,y] - location - default /A
The A option determines the location of the plot in the print window
by specifying a point on the plot that is to be aligned with a point
in the print window. You can specify the plot alignment point with
x,y in inches from the plot's origin (before PrintGL applies
magnification), or let it default to the plot center. For the print
window alignment point, you can default to the center or specify the
origin with O.
/A puts the center of the plot at the center of the print
/AO0,0 puts the plot 0,0 at the print window origin
/B - Tiling Option ---------------------------------------------------
/B[i,j,x] - tiling parameters - default /B
/B lets you specify tiling options that break a large plot into
pages. Each page is defined by the page layout option (/L). I and j
specify the number of tiles (pages) horizontally and vertically. X
specifies the overlap in inches. Displayed plots are sized based on
the tiling, but only the first tile is displayed. Use the cursor
keys to scroll the plot.
/B2,2,.5 breaks the plot into 4 pages with .5 inch overlap
/B1,1,0 is the same as /B and produces no tiling
p-10
/C - Pen Color Option ------------------------------------------------
/C[O|T]c.. - color - default /CK
/C specifies the color of each pen. The colors are B for blue, C for
cyan, G for green, K for black, M for magenta, R for red, W for
white, and Y for yellow. Unspecified pens use the last selected
color (/CRGB is the same as /CRGBBBBBB). If the output format does
not allow color then nonwhite colors are changed to black.
Additional colors can be created with shade mixing. These colors use
shading patterns to mix the eight pure colors. The format for a
mixed color is .?? where each ? represents any of the eight pure
colors. The first color is printed with the pen's shading pattern
(/S option) and the second is printed with the inverse shading
pattern. If the shade value is 0 (solid) it is replaced by 2 (one
pel checkerboard) which produces the most uniform mixed colors.
Mixed colors need line widths of at least 2 (4 for 2 pel shading
patterns) to look good, and they may have visual artifacts on edges
near a 45 degree angle. Multipass dot matrix formats may not handle
color mixing well.
By default, colors are ored into the print, so they appear
translucent. You can switch to opaque colors (overwritten into the
print) with the O suboption, and then back to translucent with the T
suboption. Make this mode switch in front of the pen that you want
to change. For PostScript devices and plotters, the color processing
is done by the device, not PrintGL. PostScript devices use opaque
colors and plotters (with standard pens) use translucent colors.
/CK sets pen 1..8 to black
/CKOR.MBT.KY sets pen 1 to black
pen 2 to opaque red
pen 3 to opaque magenta on blue
pen 4..8 to translucent black on yellow
/D - Output Destination Option ---------------------------------------
/D[+]f - destination - default /D1
The D option specifies the output printer port, device, or file. The
+ suboption causes files to be appended rather than overwritten (it
has no effect on device output). 1, 2, and 3 select the BIOS printer
routines. X1, X2, X3, and X4 select xon/xoff controlled serial port
drive. H1, H2, H3, and H4 select hardware controlled serial port
drive. You can also use the DOS devices LPT1, COM1, etc.
PrintGL cannot set up the serial ports. This is usually done in the
AUTOEXEC.BAT with MODE (probably MODE COM1:9600,N,8,1,P).
/D is ignored for display output.
/D2 sends output to the second parallel port via BIOS
/DLPT3 sends output to the DOS device LPT3
/D+TEMP.PRN appends output to file TEMP.PRN
p-11
/F - Output Format Option --------------------------------------------
/Fc[-|+[b]|*][!][~][x,y] - output format - default /FN~
The F option specifies the output format. -, +, and * are resolution
modifiers, ! selects a compression mode driver, and ~ turns off
color processing. -, +, *, !, and ~ are allowed even where they have
no effect. The display mode (b) lets you choose a display mode for
the nonstandard EVGA 800x600 mode. This must follow the format
character and it may be entered in hex by prefixing it with $.
You may enter the horizontal and vertical resolution of the output
device in dots/inch. This overrides PrintGL's normal output device
resolution, but does not affect the structure of the output format
(-,+, and * generally do alter the output structure). These numbers
must follow the format character and the display mode number.
In addition to letting you choose any resolution for a bit map, this
feature lets you compensate for print size error. For example, a
360x360 dpi printer consistently under indexes so that a 6 inch high
box comes out 5.94 inches. Using 360,363.6 (6/5.94*360 = 363.6)
removes the error.
Drivers marked below with ! have a compression mode driver, selected
with "!". This may be very useful, but it depends on your printer.
These drivers compress the output data by breaking bit map strips
with printhead positioning commands. This saves data transmission
time, but some printers spend more time positioning the printhead
than is saved by not sending the data.
A number of printers use compression mode by default. It can be
turned off with ¡ (ASCII 173).
Drivers marked below with ~ are color devices. Using ~ suppresses
color processing, substituting black for all colors except white.

Most 9 pin printers, including the IBM Graphics Printer, work best
with the /FN drivers, even if they claim Proprinter rather than
Epson compatibility. 9 pin printers with 1/144 inch indexing, such
as the IBM Proprinter and 2380, work better with the /F1 drivers.
And some not fully compatible 9 pin printers only work with /FW, the
Epson 9 pin alternate drivers.
Most Proprinter X24 compatible printers, including the IBM
Quickwriter and 2390, work best with /F5 or /FX. /F6 is only for the
IBM Proprinter X24, XL24, X24E, XL24E, and 24P.

/I - Scaling Point Location Option -----------------------------------
/IA|R|W[N] - IP point location - default /IA
The I option sets the initial scaling points (P1, P2 - the scaling
points may be set in the HP-GL file with the IP command). A
(absolute) sets the points to the default for the paper size (see
below). R fits P1 and P2 to the print window with at least .25 inch
margins and an x/y ratio of 10/7.2 (the same ratio as the HP 7475
with small paper). W fits P1 and P2 to the print window with a .25
inch margin. N makes the margin 0 for R or W and is ignored with A.
The default scaling points depend on the print window (/L option)
with the implied paper size and the plot orientation (/O option).

/O3 and /O4 gives the same default scaling points as /O1 and /O2.
/IA uses the default scaling points
/IWN sets the scaling points to fit the print window
/J, /K - Printer Code Prefix, Suffix Options -------------------------
/J[b,b,..] - printer code prefix - default /J
/K[b,b,..] - printer code suffix - default /K
/J lets you send codes to the printer before PrintGL's usual data is
sent and /K lets you send codes after PrintGL's usual data is sent.
This lets you set up and reset the printer for special situations.
These are not needed in the normal use of PrintGL.
For plotter and PostScript output, the /J codes follow the
initialization commands.
The codes are specified with byte values (0..255 or $0..$FF)
separated with blanks or commas. There is a limit of 64 characters
for any option, so very long sequences must be handled outside of
PrintGL.
/J27 79 sets skip perforation off to allow plots larger than one
page on most continuous form printers
/K10 10 sends two line feeds after the plot
p-14
/L - Page Layout Option ----------------------------------------------
/L[B][F][O][R][x,y[,x,y]] - page layout - default depends on printer
The L option defines the page layout.
B boxes the plot at the print window edge using pen 8.
F causes a form feed after the print. This is ignored for bit maps
and display output.
O sets pen overwrite mode. By default, pen colors are ored into the
print. With the O suboption, they are overwritten into the print, so
the lines are opaque. For PostScript devices and plotters, the color
processing is done by the device, not PrintGL. PostScript devices
act like pen overwrite mode is on and plotters act like it is off.
R reverses the colors on displays, bit maps, and output formats 4,
D, and L, (Canon, HP, and IBM laser printers) and is otherwise
ignored. This gives the equivalent of a photographic negative.
The first optional x and y are the print window width and height in
inches. These define the hard clip limits. These values are not
checked against the printer's capabilities. If you specify a print
window that exceeds the output device limits, the results are
unknown. You may need to reset the printer's margins or page length
for large plots (see Large Paper). The size needed for a given width
and height exceeds x and y by 8 pels to allow for line widths.
The second optional x and y are the left and top margins, measured
from the printer's left margin and current vertical position to the
print window. The top margin is modified to match the printer's
native indexing, but is accurate to .02 inch. The margins for HP-GL
and PostScript are measured from the device's 0,0 (left, bottom).
Margins are ignored for display output and bit maps.
THE PRINT WINDOW PLUS THE MARGINS MUST FIT ON THE PAPER.
Each printer has a default page layout. The default print window is
7.54x10.14 for printers and bit maps and 10.14x7.54 for HP-GL and
displays. These correspond to HP 7440 A size paper. The margins are
printer specific to compensate for different paper handling. In
evaluating user options, PrintGL processes each option and when
finished reprocesses the default page layout for the chosen printer
and then reprocesses the last user /L option. This procedure gives
good default values so that your /L option can change the letter or
size suboptions and still have good margins.
/LB7.5,3,.5,0 makes the print window 7.5 inches wide and 3 inches
high, with a .5 inch left margin and no top margin,
boxes the window, and does not do a form feed
/LF7.54,10.14 sets window equivalent to HP 7440 with A paper
/LF7.54,10.74 sets window equivalent to HP 7440 with A4 paper
/LF7.84,10.20 sets window equivalent to HP 7475 with A paper
/LF7.60,10.88 sets window equivalent to HP 7475 with A4 paper
/LF10.20,16.38 sets window equivalent to HP 7475 with B paper
/LF10.88,15.90 sets window equivalent to HP 7475 with A3 paper
p-15
/M - Magnification Option --------------------------------------------
/M[F]x - magnification - default /MF.9
The M option specifies the magnification. F fits the plot to the
print window size. The default is /MF.9 which makes the plot 90% of
the largest size that will fit in the print window. /M1 gives the
same size plot as an HP 7475 plotter.
/MF.9 fits the plot to the print window and shrinks it 10%
/M1 plots at the same size as an HP 7475
/M.5 plots at half the size of an HP 7475
/N - Page Number Option ----------------------------------------------
/N[i] - page number - default /N
/Ni says to print only page i of the plotfile. If you do not specify
i then all pages in the plot will be printed (this is the default).
/N prints all pages in the plotfile
/N3 prints only page 3
/O - Origin and Orientation Option -----------------------------------
/O[1|2|3|4[L]] - origin, orientation - default /O
The O option sets the print window origin and orientation. The
origin is one of four corners numbered 1..4 for upper left, lower
left, lower right, and upper right, and implies a plot rotation. The
L suboption specifies a left handed coordinate system, which mirrors
the plot.
If no origin is specified then printers use /O1 and displays and
plotters use /O2. This best matches the plotter's width/height
ratio.
Here are pictures of PrintGL's view of the output media compared to
an HP 7475's view, to help with choosing a /O option.

/O1 puts the print window's origin in the upper left corner
/O2 puts the print window's origin in the lower left corner
p-16
/P - Plotfile Option -------------------------------------------------
/Pf - plotfile - no default
The plotfile may be specified as the first parameter with no prefix,
or it may be specified anywhere in the option list with /P. If you
use a file name mask with "*" and/or "?", each matching file is
processed, but the first failure or user break stops all processing.
/R - Internal Resolution Option --------------------------------------
/Ri - internal resolution - default /R1016
/R sets the internal grid resolution in dots/inch. It is normally
1016 and rarely needs to be changed. To fit very large plots into
the -32768..32767 coordinate limit, use /R508. Setting the
resolution to a multiple of the output device resolution times the
magnification may yield a small improvement in print quality.
/S - Pen Shading Option ----------------------------------------------
/Sc.. - pen shading patterns - default /S0
/S assigns a shading pattern to each pen. Unspecified pens use the
last specified shade. The shade values are 0..8. 0 is the default
solid line. 1..4 are 1 dot patterns (75%, 50%, 25%, 12.5%) and need
line widths of at least three to give good looking lines. 5..8 are
2x2 dot patterns (75%, 50%, 25%, 12.5%) and need line widths of at
least five to give good looking lines. Some printers may wash out
shading because they have a dot size that is large relative to the
dot spacing. This is often the case with dot matrix printers in
multipass modes.

/S023 sets pen 1 to solid
pen 2 to 1 pel checkerboard
pen 3..8 to 1 pel dots
/T - Temporary File Option -------------------------------------------
/T[+]f - temporary file - default /TPRINTGL.TMP
PrintGL uses a temporary file when it does not have enough memory to
handle a plotfile. You can use /T to put it on a RAM disk for extra
speed. If you have 256K of free memory, it is likely that PrintGL
will never use a temporary file. You can force the use of a
temporary file, if the plot has over 1024 data points, with +. If
you use a RAM disk this may speed printing.
p-17
/W - Pen Width Option ------------------------------------------------
/Wc.. - pen widths - default /WA
The W option assigns pen line widths. Each width may be 0..9, .10 ..
.16 pels or A..I for 2..10 units of 4/1016 inch (.1 mm). A..I gives
a device independent width, but it is an approximation, limited by
the device technology. Unassigned pens use the last assigned width.
For nonsquare matrix printers, PrintGL uses pen points optimized for
an h/v ratio of .67, 1, or 1.5. Widths are figured in the direction
of higher resolution, and are not accurate in the other direction.
Line widths of over eight pels are slightly distorted at the print
window edge to fit within the four pel border.
/WA sets pen 1..8 to .2 mm
/WB2.16 sets pen 1 to .3 mm, pen 2 to 2 pels, pens 3..8 to 16 pels
/X - User Interface Options ------------------------------------------
/X[C][P][S][F][U][H] - interface options - default /X
The X option sets various interface options. C causes a break when a
plot is clipped. P causes a pause before each printed page.
S suppresses location and size messages. F suppresses location,
size, file name, and page number messages. U suppresses unsupported
command and incorrect number messages. H suppresses the help text.
/XS gives only the most important messages
/Y - Y/D Switch Setting Option ---------------------------------------
/YD|Y - Y/D switch setting - default /YD
The Y option sets the plotter's Y/D switch to D or Y. Y starts with
the plotter off and responds to esc.(, esc.Y, esc.), and esc.Z
commands. D starts with the plotter on and ignores these commands.
/YD puts the YD switch in the usual D position
/Z - Chord Angle and Enhanced Font Option ----------------------------
/Z[E]i,j - default, min chord angle, enhanced font - default /Z10,5
The Z option specifies the default and minimum chord angles for
circles and arcs. The HP 7475 defaults to a chord angle of 5 with no
minimum. Using chord angles of less than 10 returns little print
quality improvement and adds to processing time. The default is
/Z10,5. For better emulation use /Z5,2.
The E suboption says to use the enhanced font, which doubles the
number of chords on curves in text, improving the curve smoothness.
This is only effective on character heights above .5 cm.
/Z5,2 sets the default chord angle to 5 degrees, the minimum to 2
p-18
PrintGL Menu Interface (PMI) -----------------------------------------
PrintGL Menu Interface (PMI) is a menu driven program that lets you
select PrintGL options, choose a list of plotfiles, and run PrintGL.
To run PrintGL Menu Interface, enter PMI at the DOS prompt, and
press Enter. There are no command line options. The PMI main menu is
displayed at the top of the screen, and the bottom of the screen is
used differently for each main menu option. The PMI main menu is
divided by column into six groups. Each group is described below.
When the cursor is on a main menu item, the current value of the
option is displayed below the main menu. To change the value, press
Enter (or left mouse button). The options are modified with cursor
movement and typing numbers/names. The Enter key returns you to the
main menu with the new option values. Esc (or right mouse button)
returns you to the main menu with the option values unchanged.
If a main menu item includes a capital letter, that item may be
accessed immediately by pressing the letter.
When a cursor bar has a notch, the value in the notch may be edited.
PMI Menu Functions ---------------------------------------------------
The first column of main menu options is dedicated to PMI functions.
These include running PrintGL, switching to alternate settings,
exiting PMI, saving the current PMI settings, setting PMI options,
and creating a BAT file corresponding to the current PMI settings.
The "alt settings" item rotates between three PMI configurations.
The current configuration name is on line 2.
The "save settings" item saves the current PMI configurations. All
of the current PrintGL and PMI options for each configuration are
saved. The plotfile list is not saved. PMI saves its configuration
by writing to PMI.EXE. To find PMI.EXE it looks in the current
directory and then searches the DOS PATH, saving to the first
PMI.EXE that it finds.
The "menu options" item lets you set the configuration name, mouse
sensitivity, screen colors, up to five initial plotfile masks, and
the name of the BAT file created by the "creat bat" option. Screen
colors are specified with the standard IBM BIOS attributes.
For color displays, the left hex digit is the background color and
the right hex digit is the foreground color. Bright colors are not
available in the background.
0 black 4 red 8 gray (bright) C bright red
1 blue 5 magenta 9 bright blue D bright magenta
2 green 6 brown A bright green E bright yellow
3 cyan 7 white B bright cyan F bright white
"Create bat" creates a BAT file that can be run with "batfile
hpglfile /opt1 /opt2 ..". The BAT file contains the options defined
by the current PMI settings and accepts additional options.
p-19
PMI Input and Output Choices -----------------------------------------
Column two of the main menu lets you choose the plotfiles to plot
(the /P option in PrintGL), the plot page number (/N), the output
destination (/D), the output format (/F), and modifications to the
output - compression mode, device resolution override and prefix and
suffix printer codes (/J,/K).
You may enter up to 99 plotfiles in the "plotfile" main menu option.
To choose from a list of files, enter a mask name and press Enter
(the cursor must be on the mask). PMI will then display a list of
corresponding files. Select any number of the files by moving the
cursor to the desired file and pressing Space (or the middle mouse
button). If no files have been selected, then pressing Enter selects
the file under the cursor. The selected files are added to the file
list at or below the cursor. Files that would overflow the 99th
position on the plotfile list are dropped.
When you run PrintGL, PMI runs PrintGL for each file on the plotfile
list. Masks are ignored. For any plotfiles that PrintGL does not
successfully process, PMI inserts an arrow in front of the plotfile
name. You can view the results from the "plotfile" main menu item.
The arrow is not considered part of the file name by PMI, so you do
not need to remove it to retry PrintGL.
Printers that support color have a color option ("clr:" on the
menu). This lets you specify a black/white printer even though you
may have set up colors with the "pen color" menu. Output formats
that do not support color do not have this option and always convert
the selected colors to black and white.
Bit map formats let you select the resolution in the "output format"
list, but it will be overridden with the "modify output" "override
h,v dpi" option.
PMI Plot Options -----------------------------------------------------
The third column of main menu options define how the plot will
appear on the page. The options include magnification (/M), origin
(/O), position (/A), and initial scaling points (/I).
Left handed (mirrored) orientations are not available from PMI.
PMI Pen Options ------------------------------------------------------
The fourth column of main menu options covers the pen
characteristics: color (/C), shade (/S), and width (/W). Each of
these menus use the up and down cursor keys to select a pen, and the
left and right cursor keys to choose an attribute.
For color selection, the one character colors (b,c,g,k,m,r,w,y)
represent pure colors, and the two character colors are shade
pattern mixes. The shade pattern mixed colors use the current
shading option for that pen, unless the shade pattern is 100%
(solid), in which case a one pel checkerboard is used.
p-20
PMI Page Layout Options ----------------------------------------------
The fifth column of main menu options covers the page layout. The
first four items are suboptions of the /L option - box, form feed,
print window, and left and top margins. Tiling options (/B) are also
here.
Reverse image is not available from PMI.
PMI Other Options ----------------------------------------------------
Options that are generally set once and then never touched are in
column six. These include the temporary file name (/T), and under
"other", the default and minimum chord angle (/Z), plotter D/Y
switch setting (/Y), internal resolution (/R), pen overwrite mode
(opaque lines - /LO), and the pause to load paper option (/X).
Large Paper ----------------------------------------------------------
PrintGL can handle printing on paper larger than the usual 8.5x11,
but this takes some extra work. First you need to increase PrintGL's
print window to cover the large paper. This is done with the /L
option or "print window" in PMI. The print window plus the margins
(/L or "print margins") must fit on the paper.
And then you must make sure that your printer recognizes the larger
paper height. For continuous forms paper this is best done by
setting skip perforation to off, either by printer switch or with
PrintGL prefix codes. For Canon, Epson, Fujitsu, IBM, and NEC line
printers (dot matrix, ink jet, thermal) use /J27 79, or "modify
output" "prefix codes" 27 79.
And for some printers you need to increase the right margin past 8
inches. For the Canon BJC this is done with /J27 81 114.
For cut sheet paper, on Canon, Epson, Fujitsu, IBM, and NEC line
printers use /J27 67 0 n, where n is the page length in inches.
For page printers, legal size paper may be specified with these
printer code prefixes: HP-PCL printers /J27 38 108 51 65 (/K27 38
108 50 65 to reset to 11 inch paper), Canon LBP printers /J27 91 51
50 59 59 112 (/K27 91 51 48 59 59 112 to reset), IBM LaserPrinter
/J27 91 70 5 0 3 1 2 1 (/J27 91 70 5 0 3 1 1 1 to reset).
To get a 10x16 print window on 11x17 paper in a Canon, Epson,
Fujitsu, IBM, or NEC line printer, use these options: /LF10 16 .4
.25 /J27 67 0 17. You will probably need to adjust the margins (.4
.25) for best centering.
The maximum width of the print window on most narrow carriage
printers is 8 - 8/(horizontal dpi). For 300 dpi printers, this is
7.97. At 120 dpi printers it is 7.93. The maximum width of the print
window on most wide carriage printers is 13.6 - 8/(horizontal dpi).
At 180 dpi this is 13.55. At 360 dpi it is 13.57. The horizontal
print margin should be set to 0 to get this width.
p-21
Tips On AutoCAD ------------------------------------------------------
There are many ways to set up AutoCAD for use with PrintGL. Here is
a good way to start.
Configure AutoCAD for an HP 7550 plotter. Select output to a file.
Do not do any plotter calibration. Set a specific scale, do not fit.
Do not rotate. Set a plotter window that is larger than you will
ever need, 30x30 for example (this will prevent AutoCAD from
clipping the plot). Set up your plotter pen table so that each
screen color is assigned a different pen.
With PrintGL you can rotate (/O or "origin"), magnify (/M or
"magnification"), assign pens (/C,/S,/W or "pen color", "pen shade",
"pen width"), and calibrate (/F or "modify output" "override h,v
dpi"). Use /A or "position" "plot center at print window center" to
automatically center your plot in the print window.

Display Output -------------------------------------------------------
When you display a plot, the cursor keys scroll the plot, S cycles
between full, half (the default), quarter, and eighth page
scrolling, and Esc returns to DOS.
/FC drives a CGA, but does not give color.
The EGA drivers, /FE and /FM, require a 128K or 256K EGA. /FC will
work with a 64K EGA. /FM is for an EGA card with a digital (TTL)
monochrome monitor.
/FH supports the Hercules monochrome graphics card.
/FV works with any VGA card. /FV+ requires a system with 800x600 16
color support. By default /FV+ assumes VESA support. If your VGA
card does not support the VESA standard then specify the mode number
that selects 800x600 16 color mode. Here are /FV+ options for common
VGA cards ($ means hex).
ATI /FV+$54 Paradise /FV+$58 Trident /FV+$5B
Genoa /FV+$29 Renaissance /FV+$64 Video Seven /FV+$16
For MCGAs, use the VGA driver without color - /FV~.
Display output cannot be redirected to a file (the /D option is
ignored).
p-23
HP-GL Output ---------------------------------------------------------
/F8 outputs low level HP-GL, converting all characters, arcs, fill,
and clips to vectors. The output is HP 7440 compatible, containing
only IN, SP, IW, LT, PU, and PD commands. PG is added if form feed
is specified (the default). If you decline the form feed then
multiple plots may be appended to the same page.
PrintGL uses its width parameter (/W) as a pen selector, so for each
pen in the original HP-GL, you may specify a new pen in the output
HP-GL. The default /W option is /W12345678 (for /F8). Shading and
color are ignored.
PostScript Output ----------------------------------------------------
/FS outputs printable Encapsulated PostScript without preview bit
map. Characters, arcs, fill, and clips are converted to vectors, so
PrintGL is not a general purpose HP-GL to PostScript converter.
PrintGL's pen color and shading parameters are mapped into gray
levels or RGB colors. PostScript overwrites as it draws, so
overlapping lines appear as opaque colors.
If no form feed is specified then the showpage command is not
included the PostScript, and more PostScript may be appended to the
same page.
/FY appends a TIFF preview bit map to a PostScript file. To use it,
create a PostScript file with PrintGL and then run PrintGL again,
specifying the same options except /FY instead of /FS. The
destination file is appended by default. /FY assumes a PostScript
file, generated by PrintGL, is being appended. You may set the
resolution - the default is 72x72 dpi. Here is an example:
PRINTGL sample.plt /Dsample.eps/LB6,6/O2/FS
PRINTGL sample.plt /Dsample.eps/LB6,6/O2/FY

GEM .IMG and ZSoft .PCX Bit Map Output -------------------------------
Multiple pages plots, and tiled plots do not work well with bit map
output because the bit map formats have no facilities for multiple
pages in one file.
For both bit map formats, 1 is the background and 0 the foreground
for b/w files. 1,1,1 is the background for color files, with 0
representing the absence of blue, green, or red. The bit usage may
be reversed with /LR.
The bit map is the size specified by the /L option plus eight pels
in each direction. The width is extended to a multiple of sixteen
pels.
/FG creates GEM .IMG format files. The header is composed of 8 word
values, high byte first:
1
8
number of color planes - 1 or 3
repeated data pattern length - 1
pel width in microns - round(25400 / horizontal dots/inch)
pel height in microns - round(25400 / vertical dots/inch)
scan line width in pels
number of scan lines
The scan lines follow, in top to bottom order. For color plots, each
each complete scan line consists of a blue, green, and red scan
line. Data for the scan lines are composed of these commands:
$00 n b - n bytes of repeated bit mapped data
$80 n b1 b2 .. bn - n bytes of bit mapped data
/FZ gives .PCX output with the following format. The file starts
with a header composed of 128 byte values:
10,2,1,1,0,0,0,0,
max_x,max_y, (2 bytes each, in pels )
dpi_x,dpi_y, (2 bytes each )
0,0,0, 0,0,191, 0,191,0, 0,191,191, (color palette )
191,0,0,191,0,191,191,127,0,191,191,191,
0,0,0, 0,0,255, 0,255,0, 0,255,255,
255,0,0,255,0,255,255,255,0,255,255,255,
0,
color_planes, (1 or 3 )
width (2 bytes, in bytes )
1,0,..,0
The scan lines, top to bottom, follow. For color plots, each
complete scan line consists of a blue, green, and red scan line.
Each scan line is composed of these data commands:
$00..$BF - 1 byte of bit mapped data
$C1 b - 1 byte of bit mapped data
$C2..$FF b - 2..63 bytes of repeated bit mapped data

Printer Output -------------------------------------------------------
Canon BJ and BJC Printers, IBM ExecJet
For the BJ130e, BJ10e, BJ10ex, BJ300, BJ330, and ExecJet in
Proprinter mode, use /F7. This is the fastest way to drive these
printers at 360 dpi.
/FJ gives 360 dpi graphics for any Canon BJ printer in BJ130 mode.
The printer is set to 10 pitch text when finished.
You can use /FT* with the BJ or ExecJet printers in Epson LQ mode
to get 360 dpi print, but it is very slow.
These printers have an image density option (switch 1-9 on the
BJ130, 1-4 on the BJ300, BJ330, and ExecJet). Low density
eliminates every second pel. To get the full 360 dpi resolution,
use high density. For the BJ300, BJ330, and ExecJet, also be sure
that the front panel FONT HQ (high quality) light is on.
For Canon BJC printers, use /FF in Epson LQ mode. This driver uses
a graphics mode that is not supported by the BJ printers.
Canon LBP Printers
/FD works with any Canon LBP printer in ISO mode. At 300 dpi it
takes up to one meg of printer memory to print a full page of
graphics. At 150 dpi (/FD-) 512K handles a full page.
It may help to set the printer memory mode with /J27 59 27 91 50
38 122.
If the printer is in Diablo mode, PrintGL switches to ISO mode. To
switch back to Diablo mode on completion, use /K27 58.
Epson, IBM 9 Pin Printers
/FN, /FW, and /F1 cover a wide range of Epson/IBM compatible 9 pin
dot matrix printers. You need a cyan/magenta/yellow ribbon to get
color prints. The * drivers use 1/240 graphics. /FN+, /FN*, /FW+,
and /FW* use 1/216 indexing and do three vertically interleaved
passes. /F1+ and /F1* use 1/144 indexing and do two vertically
interleaved passes. /FW resets the line feed distance to 1/6 inch.
For Epson printers, the IBM Graphics Printer, and other printers
with 1/216 indexing hardware, /FN is preferred. For some not quite
compatible printers, /FW works. For IBM Proprinters and other
printers with 1/144 indexing hardware, /F1 gives better results.
Some Proprinters do not handle 1/240 graphics correctly.
These drivers use the following escape codes:
esc 3 set n/216 line feeds for all /FW
esc J index n/216 (n=2 for 1/144 index) for all /FN and /F1
esc L graphics command for /FN, /FN+, /FW, /FW+, /F1, and /F1+
esc Z graphics command for /FN*, /FW*, and /F1*
esc r set ribbon color (only if color is specified)
p-26
Epson, Fujitsu, NEC, Toshiba 24 Pin Printers
/FT covers all Epson LQ printers and many compatible printers
(Panasonic in LQ mode and others). /FF works with Fujitsu 24 pin
printers in Fujitsu mode. /F9 works with NEC 24 pin printers. /FO
works with Toshiba 24 pin printers. /FO resets the line feed
distance to 1/6 inch on completion.
For all of these drivers, you need a cyan/magenta/yellow ribbon to
get color prints. The + and * drivers use 1/360 graphics mode, and
the * drivers use 1/360 (1/120 for /FO*) indexing and reset the
line feed distance to 1/6 inch on completion. A clean paper path
with equal tension on each side is needed for good 360x360
graphics.
Many 24 pin printers are not capable of 360x360 graphics and a few
cannot handle 360x180 graphics.
The compression mode drivers (! suboption) may or may not be an
improvement with these printers.
The /FT drivers use the following printer escape codes:
esc $ absolute tab
esc * ' graphics command for /FT
esc * ( graphics command for /FT+, /FT*
esc + set n/360 indexing for /FT*
esc 2 set 1/6 indexing for /FT*
esc J index n/180 for /FT, /FT+
esc r set ribbon color (only if color is specified)
/FT does not work with IBM Proprinter X24s in alternate graphics
mode because it uses the esc $ command.
HP DeskJet, Mannesmann Tally MT92C
/FI works with any black/white DeskJet in portrait mode.
/FA drives the DeskJet 500C and MT92C, and any color 300 dpi
HP-PCL printer that supports data transfer mode 2.
HP LaserJet
/FL works with any LaserJet compatible printer in portrait mode.
Portrait mode may be set with /J 27 38 108 48 79 or you can reset
the printer with /J 27 69.
/FI works with the LaserJet 2P and 3, and any LaserJet compatible
printer that supports data transfer mode 2.
LaserJets with under one meg of memory may not be able to handle a
full page of graphics. /FL uses less printer memory than /FI, so
it may be preferred on LaserJet 2P and 3s with limited memory.
p-27
HP PaintJet
/FP drives PaintJet printers. PaintJet printers are sold with
either a serial or parallel interface. The parallel interface is
faster.
The compression mode driver (/FP!) uses data transfer mode 2
(instead of 1) and works only with a PaintJet XL.
HP QuietJet
/FQ works with QuietJets in HP-PCL mode. /J27 37 65 /K27 37 64
sets HP-PCL mode and resets to the DIP switch selected mode on
completion.
IBM LaserPrinter
/F4 drives any LaserPrinter in PPDS (native) mode. /FL will work
if the LaserPrinter is in HP LaserJet mode, but this may be slower
than PPDS mode. At 300 dpi it takes up to one meg of printer
memory to print a full page of graphics. At 150 dpi (/F4-) 512K
handles a full page.
IBM 24 Pin Printers
PrintGL has three drivers that cover Proprinter X24 compatible
printers. The printers should be in native mode (not AGM).
The first driver, /F6, is for all IBM Proprinter X24s and the 24P.
These printers do 1/144 inch indexing, and using them at 180 dpi
results in horizontal white streaks every 2/3 inch. The /F6
drivers compensate for this by indexing 19/144 inch per line,
giving 182 dpi. To work properly, the printer must be on a 1/72
boundary when the graphics are printed. If you keep the line feed
distance a multiple of 1/72 (1/6, 1/8, 1/9) then this will always
be the case.
The second X24 compatible driver is /F5 and is referred to as X24
alternate 1. This is for printers that are X24 compatible except
that they do 1/180 inch indexing. This is probably the case with
most X24 compatible printers, including the IBM Quickwriter and
IBM 2390 and 2391. /F5* works only with printers that can handle
1/360 indexing, including the 2390 and 2391 but not the
Quickwriter.
The third X24 compatible driver is /FX and is referred to as X24
alternate 2. This is the same as /F5 except that the vertical
units command uses a different format that is not strictly IBM
compatible. This driver works with Panasonic 24 pin printers in
X24 mode.
The compression mode drivers (! suboption) may or may not be an
improvement with these printers.
Proprinter X24 and XL24 printers are very slow with graphics. The
X24E and XL24E are significantly faster.
p-28
IBM Quietwriter 2 and 3
/F2 and /F3 drive the Quietwriter 2 and 3. Do not use 1 for pen
widths because Quietwriters do not print consistent 1 pel lines.
These drivers reset the line feed distance to 1/6 inch upon
completion.
Kodak Diconix Color 4
/FK drives the Color 4.
Tektronix ColorQuick
/FR drives the ColorQuick.
p-29
HP-GL Commands -------------------------------------------------------
PrintGL's HP-GL specification is taken from the programming manuals
for the HP 7475A, ColorPro (7440/17440), and 7550A. The 7550 manual
is the best reference for HP-GL - HP manual 07550-90001. PrintGL
supports the 7475, and 7440/17440 command sets except for character
set 8 (Katakana), digitize commands, output commands, the error mask
command, and some device control commands. Supported commands are
listed below. Commands that are not applicable to printing, such as
pen velocity, are considered supported but are completely ignored.
Commands that are not supported are flagged and then ignored.
In addition, PG, AF, ES, LO, character set 5, and proportional
spaced fonts, from the 7550, are supported. And fifteen pens are
allowed instead of eight.
In reading a plotfile, PrintGL ignores carriage returns, line feeds,
and nulls except where they may be valid characters (LB, SM, DT,
esc.), and ASCII EOF (026) is interpreted as an end of file mark.
AA x_center , y_center , arc_angle [, chord_angle]
arc absolute
AA moves the pen through an arc, starting at the current position,
with the pen in the current up/down state.
AF
advance full page (7550 extension)
AF starts a new plot. PrintGL starts every page with the pen up at
0,0.
AP
automatic pen pickup - IGNORED
AR x_center_delta , y_center_delta , arc_angle [, chord_angle]
arc relative
AR moves the pen through an arc, starting at the current position,
with the pen in the current up/down state.
CA character_set
designate alternate character set
See HP-GL Character Sets for a list of character sets.
CI radius [, chord_angle]
circle
CI draws a circle centered at the current position. The current
up/down state and position are unchanged by a CI command.
p-30
CP [spaces , lines]
character plot
CP moves the pen by character spaces (+ is along the text) and
lines (+ is up), using the current up/down state. Using no
parameters is the same as a carriage return/line feed.
CS character_set
designate standard character set
See HP-GL Character Sets for a list of character sets.
DF
default values
This sets default values for the following commands: CA, CS, DR,
DT, ES, FT, IW, LO, LT, PA, PT, SC, SM, SL, SR, SS, TL.
DI [run , rise]
absolute character direction
DI sets the baseline direction for labels. The default is 1,0.
DR [run , rise]
relative character direction
DI sets the baseline direction for labels. Run and rise are a
percentage of P2X-P1X and P2Y-P1Y. The default is 1,0.
DTt
define label terminator
The label terminator ends an LB command. The default is ASCII 003.
EA x_opposite_corner , y_opposite_corner
edge rectangle absolute
EA draws a rectangle defined by the current position and the
parameters. The pen position and up/down state are unchanged.
EC
enable cutter - IGNORED
EP
edge polygon
EP draws the current polygon edge. Any pen up/down used in
creating the polygon is respected in drawing the edge.
p-31
ER x_opposite_corner_delta , y_opposite_corner_delta
edge rectangle relative
ER draws a rectangle with corners defined by the current position
and the command parameters. The current pen position and up/down
state are unchanged.
ES [ space [, line]]
extra space (7550 extension)
ES adds to the space between characters and lines. The units are
in character cells (1.5*width, 2*height). The allowed range is -1
to 1. -.3333 causes characters to touch.
EW radius , start_angle , sweep_angle [, chord_angle]
edge wedge
EW draws a wedge centered at the current position. The current pen
position and up/down state are unchanged.
FP
fill polygon
FP fills the current polygon. Pen up/down commands used in
creating the polygon are ignored.
There is a limit of 2000 fill line segments per polygon.
FT [type [, spacing [, angle]]]
fill type
These are the fill types. Type 2 is identical to type 1 for
PrintGL.
1 solid lines spaced at half the pen thickness (see PT command)
2 unidirectional solid lines spaced at half the pen thickness
3 lines at the specified spacing
4 cross hatched lines at the specified spacing
5 type ignored
A spacing parameter of 0 sets the spacing to 1% of the P1-P2
diagonal. Spacing is in x axis units (this is only relevant if the
axes have different scaling). PrintGL supports any integer angle
for fill. Cross hatched lines are at angle + 90.
IN
initialize
p-32
IP [p1x , p1y [, p2x , p2y]]
sets scaling points P1 and P2
IP sets the scaling points (P1 and P2) in plotter units. P1 and P2
are used by a number of commands to help with size independent
plots.
IW [x_lower_left , y_lower_left , x_upper_right , y_upper_right]
input window
IW sets a clipping window in plotter units. With no parameters,
the clipping window is turned off.
LB..text..terminator
label
Labels use the current character set, based on CA, CS, SA, and SS
commands. See HP-GL Character Sets for font specifics.
LO [ position_number ]
label origin (7550 extension)
LO sets the label origin. The label origin relative to the label
is shown in the diagram below. For positions 4..9 and 14..19 the
label buffer is limited to 150 characters. The default is 1.
13 16 19

LT [pattern_number [, pattern_length]]
line type
PrintGL's line type patterns are close to, but not identical to
HP's. Line type patterns are dynamically limited to a minimum
length of 4 pels for types 1 and 2 and 16 pels for other types.

Pattern length is a percentage of the P1-P2 diagonal with a
default of 4%.
p-33
PA [x , y] [, x , y] ...
plot absolute
PA sets absolute mode and optionally moves the pen in the current
up/down state.
PD [x , y] [, x , y] ...
pen down
PD sets the pen down and optionally moves it with the current
absolute/relative mode.
PG [i]
new page (7550 extension)
PG starts a new plot. The parameter is ignored. PrintGL starts
every page with the pen up at 0,0.
PM i
polygon mode
PM 0 starts polygon mode. The current position is the first point
in the polygon.
PM 1 starts a new subpolygon. The position after the next pen
movement is the first point in the subpolygon. The first pen move
of a subpolygon is done with the pen up, regardless of the current
up/down status.
PM 2 ends polygon mode.
PM 1 and PM 2 close the current subpolygon with the current pen
up/down state. If used without first starting polygon mode (PM 0),
PrintGL adds an implied PM 0 before processing the PM 1 or PM 2.
The following commands are accepted in polygon mode: PM, PA, PR,
PU, PD, AA, AR, CI (circles are automatically prefixed and
suffixed by PM 1), and IN (ends polygon mode).
The polygon buffer is limited to 500 data points.
PR [x_delta , y_delta] [, x_delta , y_delta] ...
plot relative
PR sets relative mode and optionally moves the pen in the current
up/down state.
PS
paper size - IGNORED
PrintGL ignores PS. The paper size must be set with the /L option.
p-34
PT [thickness]
pen thickness
PT specifies twice the line spacing used in solid fills and may be
from 0 to 5.0 mm. It is reset to .3 mm with each SP command.
PU [x,y] [,x,y] ...
pen up
PU raises the pen and optionally moves it with the current
absolute/relative mode.
RA x_opposite_corner , y_opposite_corner
shade rectangle absolute
RA fills a rectangle with corners defined by the current position
and the command parameters. The current pen position and up/down
state are unchanged. The rectangle edge is not drawn.
RO [angle]
rotated coordinate system
RO or RO0 sets up a normal coordinate system. RO90, the only other
allowed value, sets up a system that is rotated 90 degrees. The
type of rotation depends on the paper size. This command does not
change the scaling points, so an IP command is useful after an RO.
The HP 7475 specifies two different meanings for RO90 depending on
the paper size (A/A4 or B/A3). PrintGL decides which type of
rotation to do based on the sum of the print window width and
height. If this sum is greater than 24 inches then large paper
rotation is used. Otherwise, small paper rotation is used.
Small paper rotation: Large paper rotation:
RO 0 RO 90 RO 0 RO 90

RR x_opposite_corner_delta , y_opposite_corner_delta
shade rectangle relative
RR fills a rectangle with corners defined by the current position
and the command parameters. The current pen position and up/down
state are unchanged. The rectangle edge is not drawn.
p-35
SA
select alternate character set
SA specifies the alternate character set as current. The alternate
character set is chosen with CA.
SC [xmin , xmax , ymin , ymax]
scaling
SC sets user units for subsequent drawing. The units are defined
by user values for P1 (xmin,ymin) and P2 (xmax,ymax). Using no
parameters turns scaling off, and subsequent drawing is done in
plotter units (1/1016 inch).
SI [width , height]
character size absolute
SI sets the capital letter box width and height in centimeters.
Letter spacing is 1.5 * width and line spacing is 2 * height.
Using no parameters with B or A3 paper is the same as SI.285,.375
and any other paper is the same as SI.187,.269.
SL [tan_angle]
character slant
SL sets the character slant. The parameter is interpreted as the
tangent of the angle from vertical. Using no parameter sets the
slant to 0 degrees.
SM[c]
symbol mode
SM sets symbol mode, which centers the symbol mode character at
any plotted point. Any character from ASCII 033 to 127 except ";"
sets symbol mode. Any other character turns symbol mode off.
SP pen_number
select pen
SP selects a pen. Using 0 or no parameter stores the pen without
selecting a new pen. This is usually done at the end of a plot.
PrintGL ignores any drawing with pen 0.
SR [width , height]
character size relative
SR sets the capital letter box width and height as a percentage of
P2X-P1X and P2Y-P1Y. Letter spacing is 1.5 * width and line
spacing is 2 * height. Using no parameters is the same as
SR.75,1.5.
p-36
SS
select standard character set
SS specifies the standard character set as current. The standard
character set is chosen with CS.
TL [positive_length [, negative length]]
tick length
TL sets the tick lengths used by XT and YT. The parameters are
lengths above and below the current position as a percentage of
P2Y-P1Y for x-axis ticks and a percentage of P2X-P1X for y-axis
ticks.
UC [[pen_control ,] x_delta , y_delta] ...
user character
UC specifies a user defined character. The pen control number is
99 for pen down or -99 for pen up. Pen movements are relative,
with x_delta in units of 1/4 the character width and y_delta in
units of 1/8 the character height.
VA
adaptive velocity - IGNORED
VN
normal velocity - IGNORED
VS
pen velocity - IGNORED
WG radius , start_angle , sweep_angle [, chord_angle]
shade wedge
WG fills a wedge centered at the current position. The current pen
position and up/down state are unchanged. The wedge edge is not
drawn.
XT
x-axis tick
XT draws a vertical line, with length specified by the TL command,
at the current position. The pen position and up/down state are
unchanged.
p-37
YT
y-axis tick
YT draws a horizontal line, with length specified by the TL
command, at the current position. The pen position and up/down
state are unchanged.

HP-GL Character Sets -------------------------------------------------
PrintGL supports all of the character sets that are included with
the HP 7475 and 7440/17440 except Katakana, and adds character set 5
and the proportional spaced fonts from the 7550. PrintGL's
characters are similar to but not identical to HP's.
0 ANSI ASCII
1 9825 character set
2 French/German
3 Scandinavian
4 Spanish/Latin American
5 Special Symbols (7550 extension)
6 JIS ASCII
7 Roman Extensions
8 Katakana - NOT SUPPORTED BY PRINTGL

32 ISO Norway Version 1
33 ISO German
34 ISO French
35 ISO United Kingdom
36 ISO Italian
37 ISO Spanish
38 ISO Portuguese
39 ISO Norway Version 2
The character sets specify a font for codes 033..127. Codes 000..032
and 128..255 are independent of the character set and are all no ops
except these.
003 default label terminator
008 backspace
009 half backspace
010 line feed
011 reverse line feed
013 carriage return
014 select alternate character set
015 select standard character set
032 space
Each of the character sets is available as a proportional font by
adding 10 to the set number. The proportional fonts are kerned to
improve appearance (the character spacing is adjusted to compensate
for character shape). Use the LO command to simplify working with
proportional fonts. To improve the appearance of large text, use the
ES command to reduce the character spacing.
Codes 65 to 81 in character set 5 are symbols designed to be used in
symbol mode (SM command) or as one character labels. When used in a
label (LB command) these characters are centered at the current pen
position and leave the pen position unchanged.
p-39
The HP-GL characters cannot be printed with the standard ASCII
character set. The file CHARSET.PLT is an HP-GL file that can be
used to print a replacement for this page, showing the character
sets. Use the command PRINTGL CHARSET.PLT /M1 /AO0,0 with a /F
option specific to your printer to do this.

Compatibility and Technical Information ------------------------------
PrintGL will run on any IBM compatible MS-DOS computer. It will work
in a region as small as 112K but may need more memory for high
resolution or wide prints. 144K is enough for the worst case black
only prints - 13.5 inches wide, 360 dpi. Color output requires an
additional 32K or more for high resolution or wide prints. 256K is
enough for the worst case. A larger region usually makes things go
faster by allowing larger buffers and averting the use of a spill
file.
By default, PrintGL uses the BIOS printer interrupt to send data to
a printer. The D1..D4 and X1..X4 drivers send data directly to the
serial port - addresses hex 3f8,2f8,3e8, and 2e8. If a file or
device is specified for output then DOS 2.0 file handling is used.
Messages are written to the screen with standard DOS CON output.
Graphics screen modes (except Hercules) are set up with BIOS, and
graphics screen updates are done by writing directly to the display
buffer.
PMI will run on any IBM compatible MS-DOS computer. It will work in
a region as small as 192K. When running PrintGL, all but 48K is
given to PrintGL. More memory may allow PrintGL to run more quickly.
PMI runs PrintGL via a DOS shell. It searches the current directory
and then the DOS PATH, calling the first copy of PRINTGL.EXE that it
finds. When saving the current settings, PMI makes the same search
for PMI.EXE.
PMI can use any text or graphics display mode that allows at least
80 columns and 25 lines of text. In text modes, PMI writes directly
to the display buffer, and in graphics modes, BIOS is used to
display text. When under DESQview, PMI should be started in a text
mode, and it writes directly to the DV selected screen buffer.
PRINTGL.EXE may be compressed with PKLITE, LZEXE, or other EXE file
compressors. PMI should not be compressed because it rewrites
