Photosmart C4780 error
Suddenly whenever I send anythin to the printer I get an error. When I run troubleshooting it says that there was a print job in the print queue that was preventing other jobs from printing. If I cancel the document the printer goes offline which creates a problem until I put it online then I get the original error again> I have removed and added the printer twice. The only thing that has been done to the printer lately was changing the print cartridge. Can you help?
