My favorite printer fix of all time comes from that movie quoted above. The fix being taking their office printer to an open field and bashing it to kingdom come with a wood baseball bat. I can’t express to you my loathing of how complicated printers can be to try to fix. There are so many small fragile parts that are very intricately placed together in such a way that only a trained technician can perform any meaningful troubleshooting. The most any normal PC technician can do for a printer is to replace the consumable parts (ink, rollers, maybe a drum and fuser kit) and install the correct drivers and/or software that the printer comes with.

Here is a link of a place that might provide some good advice on how to fix your printer issues
