We're printing to one of the printers from Windows XP (driver version PSCRIPT5.DLL version 5.02, apparently the lates) into CUPS and find that for certain documents the printout is mangled and the PostScript error message "ERROR: undefined OFFENDING COMMAND: CMAP-WinCharSetFFFF-H2" is printed after the mangled pages. Printing to file and printing the resultant PostScript with "lpr -o raw" results in a correctly-printed document. My guess is that pstops(1) is destroying non-DSC-conformant PostScript. (I can't post the example documents with a bug report, as they are confidential. Perhaps I could find a non-confidential document that is broken in this way.)

Perhaps we could have two queues for each of our printers, one set "raw" for use by Windows, the other a regular queue for our Linux systems, though this is a messy idea - Occam's Law and all that.

As we have found some other quirks when working with drivers based on
PSCRIPT5.dll, it would be nice to have a look into a sample file that
produces the error you describe. Pleas post (an URL to) a sample file.
