Hello OH knowledgeable ones, I have hp printer (see above for make) the model is: E709n. I am working with MAC computer. I had a paper jam and once I cleared the jam, the printer went offline. I tried turning off and on the printer. I unplugged the printer. I shut down and rebooted my computer again. NOTHING! Please help.
