-----------------  How to generate a postscript file ---------------

(0) THE LASERWRITER 7.0 WAY IS EASY

In system 7.0, it is easy to generate a postscript file.  Simply click
on the "disk file" box in the laserwriter dialogue.  The next four
procedures describe what to do with earlier versions of the
laserwriter driver.

(1) THE ONETIME POSTSCRIPT GENERATOR (PRE-SYSTEM 7.0 LASERWRITER DRIVER)

This is a fast way for people who generate postscript twice a year,
and are afraid of Apple's ResEdit resource-editing program.

Select "Chooser" from the Apple menu, and then tell it you have
appletalk hooked up (lie).  If you really are using appletalk, then
you will have problems if there is no laserwriter on the network.  In
this case, perhaps you will be forced to disconnect appletalk.

Select the LaserWriter (not the LaserWriter SC driver.)  Turn
Background Printing (PrintMonitor) off if you are using MultiFinder.
YOU CANNOT GENERATE POSTSCRIPT IF IT IS ON!  Select the LaseWriter
This will cause small formatting changes in most word processors,
since the laserwriter has larger characters than the Imagewriter or
other printers.  The changes can easily ruin a well-formatted resume.
Go to your word processor and correct the lines that have now changed.
It is a good idea to leave the laserwriter selected all the time, if
possible, so your documents are created with these changes already in
place.

Get ready to print the document in the normal fashion.  When you see
the LaserWriter dialog, click on OK and immediately type and hold
either the "k" key or the "f" key. You must depress the key immediately
within the first 1-2 seconds AFTER the dialog disappears.  Do not use
command-F or command-K, as there might be problems in depressing the
key too soon after clicking OK on the dialog.

If you get a message "looking for laserwriter", then you probably hit
the key too late.  In that case, try again; when the print dialog
comes up instead of clicking on the OK button, HOLD THE MOUSE DOWN
without releasing it.  Then at your leisure press the "f" or "k" key
and then FINALLY release the mouse.

You should see a file called Postscript0 appear in the current folder.
The next time you do it, if Postscript0 already exists, Postscript1
will be generated, etc.  When Postscript9 is generated, no further
files will be generated.

The difference between these commands is that "k" prepends the
contents of Laser Prep to your Postscript output; "f" does not.

(2) THE WEEKEND POSTSCRIPT GENERATOR

This is for people who want to occasionally generate postscript, but
also want to occasionally print directly to an attached serial or
appletalk laserwriter.

We suggest you add "Disk File" check box in the laserwriter dialogue.  It
turns out that every laserwriter icon since version 5.2 (v5.2) can
have this option [Yes, Dorothy, you can go back to Kansas].  The
system 7.0 laserwriter driver has this checkbox STANDARD.  One way
to add this box is via ResEdit:

    (a) Make a copy of the Laserwriter icon to fiddle with.

    (b) Using the latest version of ResEdit (v1.2 or later), open the copy
    and then open DITL #-8191.  Choose "Select Item Number" from the DITL
    menu, and enter number 22.  Close the Window and then choose "Open As
    Dialogue Item" from the File menu.  This should open a window
    describing a "Disk File" item, which has a bounding box of
    ((0,0)(0,0)).  This box is all zeroes, which is why the "Disk File"
    checkbox is invisible.  Change it to something useful
    ((49,314)(65,395)) and close the window.  The word "Disk File" should
    now appear in the dialogue box.  Drag it elsewhere to change
    the positioning.  Close ResEdit and save your changes.

Another way to add the box is to employ the MyPageSetup utility,
available as:
    [sumex-aim.stanford.edu]<info-mac>util>mypagesetup13.hqx

Now, every time you print, you may select the checkbox in order to
generate a "Postscript0", "Postscript1", ... etc. file.  Yet ANOTHER
way to accomplish this is by using an INIT that lets you name the
Postscript file differently, every time you print:
    [sumex-aim.stanford.edu]<info-mac>util>laser-fix-10.hqx

This method has an advantage, according to [e-mail]
(Rob Trevor).  You can print in the background (at least under system
6.0.3) if you use this method.  So you can leave the backgrounder
turned on, and the file will always go into the background folder.

(3) THE USER WITH NO LASERWRITER AT ALL

This is for people who never have access to a laserwriter directly
>From their macintosh.  For instance, people who only generate
postscript to send to a service bureau, or who always want to upload
the postscript to a remote machine.

It turns out the "Disk File" box will not stay ticked (so far as we
know), so we suggest you patch the laserwriter driver to ALWAYS
generate a postscript file.

System 5.x, 6.x drivers - Begin by making a spare copy of your
"Laserwriter" icon (because you can easily damage it permanently).
Then use ResEdit to make the following patches to the copy (note: you
will be editing a string of hex digits; do not change the length of
the string).

         Resource PDEF number 125
               location           From       To
Laserwriter  v5.0   v5.2   v6.0
         B5C    B96    C78       '57C0'    '51C0'
         B60    B9A    C7C       '56C0'    '50C0'
         B68    BA2    C84       '57C0'    '50C0'   ('51C0' for Laser Prep)
         B70    BAA    C8C       '57C1'    '51C1'   ('50C1' for Laser Prep)
         B7E    BB8    C9A       '57C1'    '50C1'

Close ResEdit and save your changes.  Now, when printing, if you
select "OK" in the dialogue, a Postscript file will always be
generated.

System 7.x drivers - Here's a hack to make the PostScript File radio
button the default, instead of the Printer radio button.  The usual
caveats apply: do this to a copy of your LaserWriter file, and don't
blame me if your Mac blows up because of this.  It works for me, your
mileage may vary...

Anyway, the hack:

1.  Fire up ResEdit, and open the LaserWriter file in the Extensions
folder in your System folder.

2.  Open the PDEF resources.

3.  Open resource ID 4.

4.  Do a Find Offset... and enter 195E.  The word before the offset
should be 377C, and the word at the offset should be 001A.

5.  Change the 001A to a 001B.

6.  Close the PDEF ID = 4 from LaserWriter window.

7.  Close the PDEFs from LaserWriter window.

8.  Open the DITL resources.

9.  Open resource ID -8191.

10. Double click on the Print button in the upper right corner.

11. Change the button's text to Save.

12. Choose Quit, or close all of the windows, saving changes.

That does it.

(4) THE USER WITH A DEDICATED COMPUTER LISTENING TO THE SERIAL PORT

This is for someone who has a workstation or mainframe listening to
the macintosh serial port.  This workstation or mainframe is connected
to a postscript printer.  The workstation or mainframe is running a
program ready to accept a postscript file and spool it to the printer.

Subject: Serial line LaserWriter

Awhile ago someone had a request for information on connecting a LaserWriter
to the serial port through a switch box. I had a similar need. I have a Mac
and a Unix box and wanted to use the printer on the Unix box from the Mac.
I didn't want to spend the money for a Kinetics box for just one Mac so I
went the route of using command-F to create a file, moving the file to Unix
and using macps to print the file. This was rather tedious.

I modified the LaserWriter driver as outlined below. The changes I made
were specifically designed to print over a serial connection from the Mac
to the Unix box, but may be useful to print to a serial connected LaserWriter.

Changes to the LaserWriter driver (versions 5.2 and 6.0)

  1) Duplicate the file and give it a useful name.
  2) Use ResEdit (or something similar) to make the following changes:
     - to simulate the pressing of command-F

         Resource PDEF number 125
       (first always write to a "file")
           location       From       To
         v5.2   v6.0
         B96    C78       '57C0'    '51C0'
         B9A    C7C       '56C0'    '50C0'
         BA2    C84       '57C0'    '50C0'   ('51C0' for no Laser Prep)
         BAA    C8C       '57C1'    '51C1'   ('50C1' for no Laser Prep)
         BB8    C9A       '57C1'    '50C1'

       (next don't create a file (still in resource PDEF/125))
            location          From         To
          v5.2    v6.0    V5.2    V6.0
          D96     E9E    '554F'  '558F'   '6038'

       (next, don't do _SetEOF to empty said file)
            location          From        To
          v5.2    v6.0
          142C    1860       '660C'      '600C'

     - change the string in resource STR number -8159 to something more
       useful than "Creating PostScript File" (e.g. I used "Sending print
       job to NeXT").

     - set resource STR number -8191 to the name of the serial port you
       will use. ".BOut" for the printer port or ".AOut" for the modem port.

     - set resource PAPA number -8192 to the name of the printer if
        you want to.

  A couple of notes: the default settings for the serial ports are 9600 baud
  no parity. So far this has worked fine but I may try changing the speed.
  When you choose the driver with the Chooser, it will turn on AppleTalk. If
  you are using the printer port then you *must* turn AppleTalk back off
  before using the modified driver.


  On the Unix end: I modified macps to "break" instead of "continue" when
  it finds the string "%%EOF" and then the command
       macps < /dev/ttyb | lpr
  can be installed in a deamon that loops forever (modify /dev/ttyb to use
  whatever serial port on your Unix box you connected the Mac to).

-------------------------------- APPENDIX --------------------------------
----------------------- OTHER USEFUL INFORMATION -------------------------
--------------------------------------------------------------------------

(A.1) FORCING THE GENERATED FILE TO GO TO ONE DIRECTORY

Postscript files are normally stored in the folder of the application
that is currently running; If you have a telecom script (Red Ryder...)
that uploads your Postscript file, it may not find this file.  We
suggest you make the file go to a pre-specified folder on your hard
disk.  Edit you Laserwriter icon via ResEdit as follows:

         Resource STR #-8191
        From        To

        "Postscript"    "HD40:Postscript"

This would put the file in the top-level directory of a hard disk
named "HD40".  Or if you just want all your files to go into a folder
named "Spool" on a disk named "HD40":

         Resource STR #-8191
        From        To

        "Postscript"    "HD40:Spool:Postscript"

etc. etc. etc.

(A.2) WHAT TO DO WHEN YOU HAVE PROBLEMS PRINTING THE FILE ON A
NON-LASERWRITER

Apple's laserprep file crashes nearly all non-apple printers (Not
cool, apple).  Because of copyright law and lawyers, we can't just
give you a modified laser prep file.  Instead, we offer two ways to
get around this problem.  One, you can use a UNIX program ("prepfix")
that edits a laserprep file to fix the mistake.  Two, you could edit
the file yourself (it takes 5 minutes and a decent editing program).

METHOD 1.  These UNIX programs will (a) edit a Laserprep file for you,
and (b) concatenate an edited Laserprep file with a postscript file;
These programs are stored in
    [sumex-aim.stanford.edu]<info-mac>unix>macps-22.shar

This is a shar archive containing two programs.  The shar archive is
unpacked using the Bourne shell and provides various documentation and
build files as well as the two c programs -- prepfix and macps.  The
first processes the LaserPrep file produced by holding down <Apple+K>
whilst printing an empty file and transforms it into a prep file which
is acceptable to most Postscript printers.  The second, macps,
processes documents produced using the <Apple+F> key to include the
processed header file.  prepfix/macps allow for the possibility of
different versions of Apple's LaserPrep.

METHOD 2.  Read the file
    [sumex-aim.stanford.edu]<info-mac>tips>imagen-postscript.txt

This file tells you how to edit a laserprep file to work with most
printers (this isn't just for imagen printers, actually).  Note: Only
Apple printers have bitmap smoothing; this is not part of normal
postscript.  If you absolutely need bitmap smoothing, and your printer
has an MC68000-family processor, and you are using the laserwriter
v5.2 icon, consider downloading the following specially hand-modified
laserprep file:
    [sumex-aim.stanford.edu]<info-mac>misc>laserprep-65-postscript.txt.

This file SHOULD NOT be used with non-MC68000 printers; it contains
assembly-language code that could crash such printers.

(A.3) DOWNLOADING A POSTSCRIPT FILE TO AN ATTACHED LASER PRINTER

A Postscript(R) file on your mac can be printed in several ways.  If
you are running system 7.0, you can use the system 7.0 "laserwriter
utility".  It is likely that this utility will work with system 6.x,
but we have not tesed it.  We RECOMMEND you use this utility because
the other methods rely on shareware software that often BREAKS after a
new system is released.  There is a good chance that Apple will keep
this utility working in the future,

There is also SendPS, a free application from Adobe.  Currently
(3.16.92) "sendps" is broken.  It is normally stored in
    [sumex-aim.stanford.edu]<info-mac>util>sendps-121.hqx
There is also something called PS Printer, a free desk accessory; or
Hyper PS, a Hypercard stack for sending Postscript files to a
Postscript printer.

(A.4) YOU WANT THE LASERWRITER 6.0 DRIVER TO GENERATE BLACK/WHITE BY DEFAULT

Here's a LaserWriter 6.0.x tip you may want to pass on. Paul Cozza (author of
SAM anti-virus utilities) came up with a patch to the LaserWriter color driver
to set B/W as the default rather than color. This speeds up most printing and I
can personally attest for the reliability with both 6.0, 6.0.1 & 6.0.2.

Using ResEdit open the LaserWriter 6.0 icon.  Make the following changes:

         Resource PDEF number 4
           location       From       To
        18F3      0017        0018

This will change the radion button default to B&W.

Or, if you have a sector editing program
such as "Fedit" or "Copy II Mac", search

for the string   "377C 0017 0004 7801"
and change it to "377C 0018 0004 7801".

(Block 141 Part A via Copy II Mac)

This will change the radio button default to B&W.

(A.5) YOU WANT TO PATCH THE LASERWRITER 5.2 DRIVER TO COEXIST WITH
PEOPLE USING THE 6.1 AND 7.0 DRIVERS

If anybody is interested, I've worked out a way to patch the LaserWriter 5.2
driver so that it will coexist on the same shared printer with people
using the 6.1 or 7.0 drivers. The principle of the patch is very simple:
give the PostScript dictionary a name other than "md"--voila! You can have
both the old and new dictionaries loaded, without having to reset the printer.

What I did was change the dictionary name to "md68". In the
"LaserWriter" file, you'll need to patch occurrences of "md" in the
"POST" resources numbered -8161, -8158 and -8156. In the "Laser Prep"
file, you'll need to patch the "POST" resources numbered -8192 and
-8179. Make sure you don't alter occurrences where "md" is part of a
longer word (e g "mdf", "systemdict").

By the way, I did my patching with DeRez and Rez. ResEdit 2.1 doesn't
correctly handle "STR#"-format resources (which is what POSTs are) which
have zero-length strings in them. I haven't checked if the bug is fixed
in 2.1.1.

(A.6) YOU DO NOT WANT THE LASERWRITER DRIVER TO MONOPOLIZE THE APPLETALK PORT

If you're always generating a postscript file to disk, you may not
want the laserwriter driver to monopolize the appletalk port.  For
instance, if you have a "Freedom of Press" Postscript interpreter and
a deskwriter connected to the printer port, the laserwriter driver
barfs all over your deskwriter every time you select it in the
chooser.  There is some hope that this procedure can alleviate the
problem.  This information comes from Brian Mathews ([e-mail]).

I just figured out how to do this the other day.  Here's how (this is
on the 7.0 LaserWriter.  It should work on earlier LaserWriter's, but
I haven't tried it).  The usual warnings apply: only do this on a copy
of the LaserWriter file, don't blame me if your Mac blows up, and don't
distribute the modified copy.  The following works for me on a Plus
running 7.0, but your mileage may vary...

1.  Move the LaserWriter file out of the Extensions folder.

2.  Open the Chooser and close it.  These first two steps are
necessary because the Chooser caches some flags we'll change in a bit.
Unfortunately, it doesn't seem to check the modification date of each
file and update its cache if the file's been changed.  Grrrr.

3.  Fire up ResEdit and open the LaserWriter file.

4.  Open the PACK resources.

5.  Open PACK #-4096 (it should be the only one).

6.  Look at offset 000C into the resource.  There should be an E0D2
(for LaserWriter 7.0.  For earlier LaserWriters, the number may be
different, but the top bit should definitely be 1.)  If there isn't,
stop now.

7.  The top bit of the word (actually the top bit of the long word)
at 000C is the Appletalk bit.  Turn it off by changing the byte at 000C
>From E0 to 60.

8.  Quit ResEdit, saying to save changes.

9.  Put the LaserWriter file back into the Extensions folder.  It's
easiest just to drop it on the System Folder and let the Finder scoot
it into the Extensions folder.

10. Open the Chooser, and click on LaserWriter.  It shouldn't turn on
Appletalk, so both of your serial ports are free.

If you accidentally try to print (really print, as opposed to just saving
the file) with the modified driver, it simply tells you AppleTalk isn't
active.

I've combined this with the hack I posted yesterday to make saving
to a file the default choice in the Print dialog, so it's very easy
to flip on the LaserWriter and save off a PostScript file.

(A.7) YOU WANT TO CHANGE THE DEFAULTS IN THE LASERWRITER DIALOGUE

D.G.Gilberts's MyPageSetup Program allows you to alter the defaults on the
currrently-selected printer driver. We have been using it for years.
Latest version 1.3 is available via anonymous ftp from the usual sites.

 (including src.doc.ic.ac.uk, in mac/sumex/util/mypagesetup-13.hqx.Z
  - don't include the ".Z" in your "get" command and it will automagically
  be de-compressed back to plain binhex for you on the fly !)

>From Mark
I just got StripFonts (HappiWare by James Elliott) to work here.  (It
took me a while because there is a unix end to the package, and I'm a
novice at unix).  It's great at stripping fonts that already exist on
your postscript printer (typically reducing file sizes by 90% or more).
This in turn shortens mac/unix transfer times and printing times.  I
applaud James for his work -- StripFonts is the solution to the slew of
postings I've read about huge sys7.0 postscript files.  Below is James
posting from about two weeks ago (I trust he doesn't mind me spreading
the word).  BTW - why hasn't it made it to comp.binaries.mac yet?

>From Axello
To select which fonts to download to the laserprinter and which fonts
to ignore, there is a nice CDEV which controls all this and it also
lets you select if the LaserPrep must be included or not.  It's
'Trimmer', made by Hugo Ayala. It's available from:
    [sumex-aim.stanford.edu]/info-mac/cp/ps-trimmer-101.hqx
