Firefox will disable my HP L7680( error message " turn power off then on again") when using either the printer icon or print in file pull down. .
This happens for em & other print request in my online brokerage account. It has no problem printing PDF files. When the message appears, four lights start blinking at the same time on the auto answer button, on off button, lower SD slot, and the light under the OK button with the directional tabs. At that point I have to power down the printer and change to ie8 to print these. My ie8 browser has no problems with any printing, but it does not function when trying to add notes in my Comcast address book
