hello,
I can trying to print using the terminal on Ubuntu 12.04 to a tray 2 on a HP Color LaserJet 4700. I am using the command lp with the option "-o InputSlot=Tray2" and it continues to print to the tray 1. I changed the default tray to tray 2 and still prints from tray 1. if i print from other applications like libreoffice or gimp it automatically prints to tray 2. Any assistance would be appreciated.
