Epson WF3640 paused printing - a solution
My MacBook Air showed printing paused when trying to print to my Epson WF3640.
I saw another post saying to reset the printing system and select the printer name instead of Secure Air printing.
This isn't work on mine HOWEVER what did work was changing it to Air Printing.
Hope this helps as this problem came out of nowhere - no OS updates or software updates.
Mac mini, OS X 10.11
