I have a Dell Dimension 5150 with xp. Because of the lack of xp support I have installed Ubuntu 14.04 LTS in another partition. It seems OK, but I am unable to print. My printer is an HP PhotosmartC7280 All-in-one.
I can print the Ubuntu printer test page, but as soon as I try to print anything else nothing happens. I have tried to alter the printer default, but although there are several printers available in the printer folder, none of them will work. I am still very new to Linux, so if anyone has advice for me, please make it extremely simple, with all the steps explained. Thank you.
