I'm new to Ubuntu (using version 12.04 LTS), so maybe there's something obvious I'm missing. I hope that's the case. I'm on my second printer, and keep having the same problem. I'm currently using an HP Deskjet 2514. The system recognizes the printer and attempts to use a driver for HP series 2500. When I try to print a test page, though, I get to "Idle - Rendering completed" and the page never prints.
From what I can tell, I've got HPLIP installed, but I don't know if there's something I need to do that I'm not doing. From what I've read, it seems that the 2514 should be supported, but it's not working.
Incidentally, my first try was with a Canon Pixma MG2520, and it did exactly the same thing.
