I first experienced this at work on an Asus machine with an i7-3770 CPU, 16GB of RAM. I connected an HP Laserjet 1020. Xubuntu appeared to configure and install a driver, but wouldn't print a test page. (Not an issue with other printers on the same system) So I tried changing the Make and Model of the printer. When I clicked Change beside the Make and Model dialog box the Change Driver "Searching" dialog appeared, but it just sits infinitely looking for drivers.

I thought it might be some odd relationship between the machine and printer so I tried a different system at work and a different printer (a brother printer which Xubuntu found and printing worked). Same issue trying to change the Make and Model. Also tried at home thinking it might be an issue with our PXE installed Xubuntu, but same issue (USB installed).
