I had recently upgraded Adobe Reader to version 10.1.2 and my printer would only print a blank page when I tried to print a PDF document. The printer lights would blink, and all print jobs after that would not print until I physically rebooted the printer. I thought there might be something wrong with the PDF that I was trying to print until it happened to me again with another file.
I came across a knowledge base article from Adobe last updated 1/25/2012, http://kb2.adobe.com/cps/928/cpsid_92870.html that gives a link to a patch for being unable to print at all, and it mentions that Duplex is set to “ON” by default after the upgrade.
Unchecking the Duplex option allowed me to print successfully. The patch may help others in troubleshooting print problems. As Adobe Reader updates get installed on our customers’ PCs, we may have an increase in support calls.
