As part of my experimentation of using a laserwriterII on the on ethernet
connected to PC's and Mac's I am now testing NCSA Telenet and FTP to send
Mac files dumped in postscript (files created using the k or f key while
printing from particular documents). I am able to create postscript files
that work fine when I dump them to my local laserwriter IINT with the
application SendPs. However when we FTP these files to a MS-DOS system that
is hooked to another laserwriter IINT we get problems. The postscript file
is sent just fine. The second IINT is hooked via the serial port to a net
work of MS-DOS machines. We take these postcript files and "print" them to
the laserwriter IINT, it takes them, the light flashes for awhile then it
stops after a reasonable period, but we get no printout. My question has to
do with what happens to the laserwriter IINT when it is set for the serial
port rather than Appletalk and how it interacts with the postscript files
that we have created on the Mac. Is there a difference in the modes of the
printer when it is set for the serial port that requires some subtle changes
in the postscript files that were transfered from the Mac?? Below I have
included the test postscript file we dumped to the printer from the MS-DOS
serial connection. I have deleted the middle portion with most of the hex
code for the graphics and left all the beggining and trailing postscript
that was created by pressing the "f" or "k" key on my Mac:

Well there is the postcript file that I had created on my Mac. Can any of you
postscript experts out there tell me why it won't print anything on a
laserwriter IINT hooked to MS-DOS machines via the serial port, but will print
fine for a IINT hooked via Appletalk directly to a Mac?? Any input would be
most greatfully appreciated!!!
Thanks in advance for your help!

Usually, when these files are printed from an Apple, the definitions are downloaded once to the printer and stay resident after that. From an MS-DOS machine, this does not happen. However, if you hit cmd-K the postscript file you get will have the Apple header. For some reason I am not too clear on it must be edited somewhat, but then it can be attached to the file and printed from any machine without leaving the definitions resident. If you are inclined toward programming, you can probably figure out the details of how to get around this from a public domain package called "macps" the source of which you can get from sumex.stanford.edu by anonymous ftp. Look in /info-mac/unix. -- Mark Wilkins

I recently grabbed a program from America OnLine that is called AddLaserPrep, (or something like that - I do not have it in front of me). Anyway, it is suppose to read in a Command-F Postscript generated file and put into it the correct LaserPrep dictionary with the correct edits. Since I do not have a non-Apple Postscript printer, I cannot tell you how well it works. I will be submitting it to comp.binaries.mac shortly since I did not see it on sumex.stanford.edu.

Look in /info-mac/unix. For a dos machine this could give some clues but from what I've seen macps is pretty sophisticated (a good piece of software in my mind anyway). A much simpler hack that can provide simple document capabilities is to add the two lines: %! serverdict begin 0 exitserver to the beginning of a ps file generated with COMMAND-K. I'm not sure exactly what it does (how's that for honesty?) but I used it for quit a while before I discovered the wonderful macps. Note that I never tried it with graphics or non-resident laserwriter fonts but it seemed to support basic operation ok. By the way, I can't remember if the dos editor can handle it or not but in order to add these two lines to the beginning of the file might be tricky as a COMMND-K generated file can have lins that are extremely long (had to use the cat command in unix to handle this). good luck -- Jeff Wiseman: ....uunet!tellab5!wiseman OR wiseman@TELLABS.COM
