I have a problem with all GTK apps (evince, gedit, Firefox, gimp) not seeing my installed printer. When pressing Print, I can only choose Print to file, my printer is not shown. So I can not print PDF documents, websites...
In LibreOffice, the printer works.
How can I get the printer to be seen by the apps and print PDFs?
Some more information: It is a network printer (hp). When a document is printed from LibreOffice, the printer is shown for a few seconds as printer in the other GTK apps. Then disappears again.
