Error 79

[1Gregory]

I have used this printer without issues for many years on the same exact setup, but all of a sudden it has developed this issue. When I print the dialog box shows that it has successfully connected to the printer, and the printer lights indicate the incoming page. Then the printer display indicates printing for a few seconds, immediately switching to Error 79. If left alone the display will go back to normal/Ready.

I have reset the printer (Off/On) many times, reset my router, deleted and reintroduced the printer from the Mac Print Center, tried using HP Easy Start. Nothing works -- can no longer print.

Please help!

Thanks for your help! I'm all set now. Turns out there was an issue with a particular file that I was trying to print -- a receipt from a big box store. Strangely, the perfect looking PDF I downloaded wouldn't print, and neither would it print using the "Print" option on the website. Once I tried another doc the printer was working. Odd.

Anyhow, thanks again!
