Comment 33 for bug 1020048

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.
