Well...
   I just compiled macps 2.2 on my SparcStation. I then uploaded a 6.0
laserprep file and a MicroSoft Word print file using NCSA Telnet. I
followed the instructions included with macps. I then sent the resulting
file to an Imagen ImageServer 7320 running TURBO UltraScript 4.1T Rev. B.
It printed without any problems. Macps automatically edits the laserprep
file which Imagen had done by hand. The pieces that are edited are
eexec/cexec sections and the statusdict operator setdefaulttimeouts. Note:
eexec/cexec are NOT documented in the red book (yes, Glenn, the "PostScript
Red book" :) ). The statusdict operators are NOT part of the language, they
describe an implementation specific feature. We probably should have set
up a compatible dictionary but since we have other methods to timeout/end
a job, it was not deemed necessary. If there are further problems with
macps/prepfix, please call Imagen Technical Support at (408) 986-9400. If
they do not know about macps, tell them to talk to me. It would be helpful
to know version of the printer software and whether any other LaserPrep
files have been run on the system. Also, the error message produced would
be of use.

   I think I'll bow out of a discussion of PostScript clones due to the
recent postings. I will say that our interpreter was written from scratch
and that we leveraged off of the work done for DDL. We feel we have a very
robust and complete interpreter. There will always be an epsilon value
where we differ from Adobe PostScript but we are striving to approach 0.
Remember, just as Unix systems are not all the same, neither are
PostScript (the language) printers. You must choose the printer (or
Unix system) that meets your price/performance/functionality
specifications. Our company (QMS) provides both Adobe PostScript and
Imagen UltraScript printers and both sell quite well.
