I bought an hp deskjet 697c printer from the thrift store w/no paper work manual or disc...it turns on & installed to my computer but won't print anything even a test page. On the spool it just says error & a balloon comes up that says printer failed to print document. I pushed the resume button & a page printed that said paper mismatch so I kno it works but why won't it print anything I send to it. I have done numerous troubleshooting...restarting computer...reseting printer..reinstalling port...changing ports...changing spool properties...checked all plugs & cables...ink is full & properly installed...i was going to install a new or different driver but it says that the proper driver is installed for this printer for windows xp which is what I have...nothing seems to work. Please help me resolve this problem I don't kno what else to try...Thank you
