I have a HP P4014 that I just upgraded to version 4.260.1 and now when I print from Word it automatically duplexes the document even tho duplex is turned off on the printer and in document setup.This only happens when I set the tray to anything but plain paper. If I have it set to plain paper it prints fine. It happens on both tray 3 and 4. I have not tried 2.
