Here are some suggestions that work for me.

1. Get ehandler.ps from the adobe server and make sure that it is 
   downloaded and resident in your laser printer. This way, if you
   do get an error, at least you will get a printout of the cause
   of the error, and more importantly, a hardcopy dump of the stack
   contents.

2. If you have a MSDOS machine connected directly to your laser printer,
   you can use a terminal program (such as kermit) that will allow you
   to send the file (ASCII upload) and see what the printer responds
   with. Also, you can place the printer in executive mode and try out
   various PS commands and get immediate responses on your screen.

   You can also do this with a unix connection, use  CU or TIP to
   connect to the ttyport that the laser printer is connected to
   and place the printer in executive mode. Executive mode doesn't
   kill your job when you create an error, prints out the cause of the
   error (on your terminal) and you can see the stack using
   pstack or == etc.

To get the ehandler, send the following message to
adobe!ps-file-server@decwrl.dec.com

send programs ehandler.ps


Be sure to change the password that is stored in the ehandler to match
the password for your printer (0 is the default) and send the file to 
the printer.

Hope this helps.

! following is a quick script of a simple  executive session with
a PostScript printer connected to a unix system via a terminal server.
