I wanted to print a document out of Libreoffice-Writer from my netbook (which is connected via Wifi with the router/network). The printer is connected to my desktop PC (via USB) and is shared via the network. At first my desktop was of, so it is clear that the printer wasn't shown in the printer list of Libreoffice. But then I turned on my desktop and expected that the printer would appear in the printer list. But he didn't appear. This occurs every time the printer is off, and Writer is running.
I've tested it with other applications (Evince and Firefox) and there it worked fine.
I had to restart Libreoffice to make it recognize the printer.

Importance -> lowest trivial due to incredibly easy WORKAROUND: Restart LibreOffice.
