I've got an HP OfficeJet Pro 8500A Plus all-in-one printer/scanner. It's setup to use wireless connectivity to my home network. Every PC and laptop can, and has, printed to it fine, until Saturday. Then suddenly nothing and print to it. On every PC and laptop if we submit anything to the printer it goes into that PC/laptop's queue, and there it sits, until I delete it from the queue. I've run a test print job, and that works fine. I downloaded the HP Print and Scan Doctor 2.0 app, ran it and as far as it is concerned everything fine. The only way anything can print anything to the printer is to reboot the machine that has submitted something to the printer, which frankly is very inconvenient.
What would cause my OfficeJet Pro 8500A to stop printing all print jobs?
