Be sure to do a 'device,/close' command after issuing your postscript
commands. If you don't, the file is still open, and printing it will often
give you only partial or garbled output.

here is a copy from a recent post by Mike Schienle who maintains the
FAQ:
<http://www.ivsoftware.com:8000/FAQ/> is the location for the FAQ.
< http://www.ivsoftware.com/pub/faq/IDL_FAQ_Update19990515.htm l> is a
snapshot containing the changed or added items from
May 01, through May 15,
1999.
<http://www.ivsoftware.com/pub/faq/IDL_FAQ_19990515.html> is a snapshot
containing the latest version of the FAQ as of May 15,
1999.
Also, check out the Coyote website by David Fanning:

If your boss gives you books about IDL, ask him to purchase David's book
(which he can do from that website)!
Regards,
Martin.

Hooray for you! :-)
You can find the FAQ here:

Well, you could be doing any number of things wrong. You may want
to read the series of articles on my web page entitled "Producing
Perfect PostScript Output" for some clues:
http://www.dfanning.com/documents/tips.html
My guess is that you have set the PostScript page up in such
as way that you are clipping the plot. My program PSWindow
might help you out with this. It creates a window on the PostScript
page with the same aspect ratio as your display window:

Your boss is giving you the wrong books. :-)
