I am using the printer driver "Postscript File" from windows to generate a postscript file on disk from a windows application on a pc. Then I upload the postscript file to a unix system via kermit and try to "lpr" it onto an apple laserwriter, which promptly flashes and gives up. With the macintosh there are laserprep files which must be prepended to any file in order for it to print out. I imagine there is a similar "prep" file for windows, right? My questions: 1.Is there any way to get windows to include the prep file (if it doesn't) in the postscript when the ps file is generated, or does the printer handler take care of it? 2.Is there are program which runs under unix which will automatically prepend the windows "prep" file? If anyone has done this, could you please let me know the procedure. Thanks bunches, Marcos Salganicoff General Robotics and Active Sensory Perception Lab

As an update to my own posting: I ran the postscript output file through and X postscript previewer (after commenting out Laserwriter specific stuff like "statusdict") and found that the problem was that the windows ps driver was dropping spaces between keywords causing the interpreter to bomb out. After hand inserting the appropriate spaces the thing prints out just fine. Also don't forget to delete the ctrl-d at the beginning and end of the file.

I generated an .EPS file from WfW and was able to print it on a PC connected to a PosatScript Printer without windows by executing the following set of commands: copy /b header.eps lpt1: copy /b word.eps lpt1: I uploaded both the files on a Unix system (both as text and binary) but when I tried to "lpr" the header file, the printer spot out a page with a line "Error in binary file" printed on that page.

Here's the story:
First off, Windows puts a ^D at the start of a file, and Unix chokes on this,
as well as any ^D in the file. It must be deleted. Also, the first line
must be a %! all alone (Apple seems to prefer it that way).
We have written a small program that will play this little game for you.
It will run under Unix or DOS.
Individuals may feel free to use this program. _ANY_ organization or

Here's the code:
/* PSFIX - Will patch a postscript file for proper printing by
adding '%!' at the top of the file, and by eliminating
any nulls and control-d's in the file.
This patching is necessary when printing to Apple Print
Servers via LocalTalk, or when printing postscript to a
file from MicroSoft Windows 3.0.

My questions: > >1.Is there any way to get windows to include the prep file (if it >doesn't) in the postscript when the ps file is generated, or does the >printer handler take care of it? > Correct. However, this is automatically done whenever you print, unless you turn the option off. The keyword you're looking for is "Header", which can be inclucded/ignored unter the Postscript setup option under Control Panel / Printers. You want it on. It might be possible to print the header separately and never again, but I haven't gotten that to work on our system. >2.Is there are program which runs under unix which will automatically prepend >the windows "prep" file? Nope. Like I said, it's Windows thing. You have to send the file in raw mode thought (on our system, it's "lp -oraw"). Our system can detect a postscript file and switch to raw mode automatically, unless it's a strange postscript file. ----------------------------------------------------------- The Time Traveler I used to love her a.k.a.

I have acquired W4W only about a week ago, and I have been able to print to a file (in PostScript format), apload to a Unix system (using kermit) and send files to an Apple Laserwriter II (among others) without any problems! I am not an expert on this but I just happen to know that this works fine for me.

As a followup: It turns out the windows postscript driver sometimes uses a lf character to seperate lines in the output file. When I used microemacs to delete the ^d at the beginning of the psfile and saved the result the lfs were removed, ergo my keywords were smushed together and the psfile was unparsable ==> Don't use microemacs to diddle ps files from windows.

A sed script works quite well also ....
