OPI is **THE** Holy Grail the print industry is looking for. The trade mags
mention Linux as a curiosity and of the few sites that use Linux, the stumbling
block to full deployment is the lack of a good OPI solution. Unless the site was
using it solely for file- and non-OPI print services, there's always the OPI
caveat mentioned in the articles. SIGH.

The leading solutions are either NT-based (ScenicSoft's "Color Central" or
IPTech's "CanOPI") or commercial Unix-based (Xinet's "FullPress" or Helios'
"EtherShare").

In principle, all it needs to be is a filter for a printer queue. The filter
would grep the PostScript stream and every time it sees an OPI "Comment" it
grabs the filename listed in the comment and substitutes the file for the
comment. Naturally, all kinds of intelligence needs to be built in to the filter
for validating the OPI comment and dealing with the potential for super-hairy
filenames which are, unfortunately, common on Macintosh volumes.

CanOPI from the list above does the file substitution on the fly while most of
the others (I'm not sure about FullPress) write a new (larger) file as the input
job is processed. CanOPI's method is slick since it minimizes diskspace
requirements on the OPI server and the read/write penalty.
