Today  I really had to fix my printing (or inability to print) problems using Fedora 15.   So far I’ve been trying to print on a network printer and hadnt had much luck there (I can see the printer, the print job seems to have been sent, but nothing gets printed).  I reckon I’ll give printing locally a try.  I attached the printer (its an HP 1020 laser printer) to my laptop and F15 detected the printer but still would not print.  Well according to some posts on the web, while F15 ‘detects’ the printer the appropriate HP plugin still needs to be installed.. hmm.. I thought I did that already, anyway here’s the quickest fix:

1. sudo yum install hplip-gui
2. sudo hp-plugin  <– running the plugin installer using  sudo — ie using your non-root account — will prevent “QGtkStyle was unable to detect the current GTK+ theme.” errors.

step 2 will launch the GUI installer and install the necessary components to (at least) print locally.  I’ll know later if this also fixes my network printing problem.
