I recently had trouble printing out some postscript files which I had
received over the net.  I tracked it down the problem and discovered
that the computer and printer where only talking to each other in
7-bits, but the files had some 8-bit codes.  I had never noticed this
problem before because most software will send these codes as octal
escape sequences.  So I wrote up the below attached filter to convert
any stray 8-bit characters to their respective octal escape sequences.
Nothing all that special, but it could save someone a lot of work 
someday.  Also I strongly recommend anyone distributing postscript
documents to use this filter to save headaches.

(If anyone has a /etc/printcap that lets a Apple Laserwriter + and
Sun Sparcstation 1 talk 8-bits, please let me know!!)
