There is another workaround which is probably more reliable and suitable for any duration of LibreOffice session: Switching LibreOffice to the standard GTK print dialog (the dialog used by Evince, Firefox, GEdit, and many other GNOME/GTK apps). You will loose the embedded preview in the print dialog but otherwise printing works and you have one printing UI for most apps.
Proceed as foilows: - Open LibreOffice - In the main menu (top bar) choose "Tools", then "Options". - In the pop-up dialog click "General" in the "LibreOffice" section on the left. - On the right, near the bottom, mark "Enable experimental (unstable) features". - Under "Print dialog" unmark "Use LibreOffice dialogs". - Click "OK". - Return the timeout values in the CUPS configuration to their original (default) values (if you had changed them). >From now on, whenever you want to print out of LibreOffice you will get the standard print dialog and not LibreOffice's own dialog. Please check, especially on longer sessions or when leaving LibreOffice open over night, whether always the list of available printers appears correctly in the dialog and whether you can print. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to libreoffice in Ubuntu. https://bugs.launchpad.net/bugs/1020048 Title: after certain time printing to cups stops working Status in LibreOffice Productivity Suite: New Status in “libreoffice” package in Ubuntu: Confirmed Bug description: in our institution we are running only printers through a cups server. while freshly opened document prints well, after some time (few minutes) clicking "print file directly" and menu item "print" do not work any more. after close and open again, thing prints correctly. i have checked what exactly is going on in such cases and logs on the cups server don't show any submissions and/or errors so that the thing is obviously stopped at the level of libreoffice.
