I do not know what has happened. My HP LaserJet P1102w has stopped printing two sided documents. I have it on a MAC Pro Tower running OS X ver. 10.9.1. My software is up to date.
When I go to print two sided, it prints one side, and it no longer tells me to feed the paper and hit duplex. It creates an error and I have to turn the printer off, and print only one sided copies.
It worked fine for the longest time. Has anybody run into this problem? It started before I installed Mavericks OS.
Thank you for your help.
