In Fedora 7, we have had a problem crop up lately on some laser printers (not all laser printers). WHen users try to print pdf documents from Evince, the printer flashes "processing document" but never finishes. Until today, the jobs would pile up in the print queue and the system would start to act as if the printer was not enabled. I mean, in system-config-printer, the "enabled" box would become unchecked. After updating cups today, I found that the pdf print jobs from evince do not "clog" up the printer, they just disappear from the print queue. The printer stays enabled, it just fails silently after flashing "processing document". That's better than turning off the "enabled" status, but not by much. However, the Adobe Acrobat reader does open and print all the pdfs. We have tested sending files to the printer with "lpr file.pdf" and it works only on small files. I don't understand why more people are not complaining. This makes me think it is a problem of a particular kind of printer, since some printers here work, some don't. One that does not is a HP laser 4050 with 4 meg of memory, while one that does work is an HP Laser 4M with 4 meg memory. There are no errrors in the /var/log/cups files, just lists of files printed. I searched in the fedora bugzilla and there's nobody there complaining that Evince won't print in this way, but I did google more broadly and I find users from other Linuxes talking about it. Here's the Ubuntu complaint https://bugs.launchpad.net/ubuntu/+source/evince/+bug/44989 http://forums.fedoraforum.org/showthread.php?t=150782 There is a lot of wild guessing about what might be wrong. Is the finger of blame pointing at CUPS, pdftops, dbus, poppler-utils, xpdf, or what? -- Paul E. Johnson Professor, Political Science 1541 Lilac Lane, Room 504 University of Kansas
