I can print from every other app!
It goes through the in-app process but then it stalls on "Printing - Looking for printer…" in the queue. The printer shows as being "in use" in the preference pane.
Please note that, while these are my current configurations, this was happening before I upgraded OS and Acrobat(s):
Mac OS El Capitan
EPSON WF-3540 (USB connection)
Acrobat CC 2015
Acrobat Reader DC 2015
I look forward to hearing any ideas as to how to remedy this!
Thanks!
