Simple printing setup. 3 machines, 2 printers. One prints invoices, other prints misc documents.
We use $300-400 range dell laser printers. Usually they work great. 3 times now, we have replaced the printers with the same and different models. Often going to the next model up or newer.
For no noticeable reason, A printer will start acting up. Test pages and documents output gibberish. Sometimes hundreds of pages that don't stop until we power cycle. Regardless of the spooler queue.
Reinstalling printer and drivers do not help. Due to wiring constraints, the printers are each attached via USB and shared over the network.
