Your original bug report (haven't read the postings below that) looks like your original print file is content with some issue, so that what CUPS' pstops filter sees coming along has a problem (like not being compliant as "DSC PostScript") it cannot process correctly.
It could also be a problem of the application generating the PostScript print file. Which filetype are you trying to print from which application? Can you post a link to the file, so I can have a look? -- cupsys in combination with xpp https://launchpad.net/bugs/49063 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
