CUPS 1.6.2 got released on Monday and I have packaged it for Raring. It seems that exactly this problem was addressed in this version of CUPS. See
http://www.cups.org/str.php?L4187 So this should be fixed now in Raring. Please test by undoing the workaround from comment #33 and updating your Raring system so that you get the new CUPS. If this helps please mark the LibreOffice tasks invalid. ** Also affects: cups (Ubuntu) Importance: Undecided Status: New ** Changed in: cups (Ubuntu) Importance: Undecided => High ** Changed in: cups (Ubuntu) Status: New => Fix Released -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1020048 Title: after certain time printing to cups stops working To manage notifications about this bug go to: https://bugs.launchpad.net/df-libreoffice/+bug/1020048/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
