I can print multiple copies from Word, Excel, the Internet, without any issues. I've uninstalled and reinstalled Adobe Reader DC. I've Uninstalled Adobe Reader DC and deleted every Adobe folder I can find, restarted the computer, and reinstalled Adobe Reader DC and it still does it. I've created a new user account and printed a .pdf document from the old user and it still prints 5 copies whether I tell it to print 2 or 3 or 7. It will print 1 copy fine. I can print 1 copy 3 times and get my 3 copies but I cannot tell it to print 3 copies from Adobe Reader DC and get anything but 5 copies.
