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. Mark ---- Name: Mark Peek Mail: Imagen Corp. 2650 San Tomas Expressway, P.O.
