Lexmark Z35 printer
 

My Lexmark printer has been working great up until about two days ago. I tried to print several things and none of them would work. I turned my computer on today and the items are still in the spool to be printed and try to print everytime I turn my computer on. The printer isn't showing up in the printer user interface and everytime I try to cancel it with the cancel command in the shell, it says client-error-not-found. Please help. I want control of my computer back from this demon printer.
