How to troubleshoot the printer
Printer problems always appear at the worst time. Here are some ways to get your printer working again if you're printing from your PC, phone, or tablet. Printers are great when they work, but when they don't they can be extremely frustrating. Here's how to solve some of the more common problems, including not printing at all until blocked nozzles and other problems.
