I have an HP 4050 printer, that is a local printer on a station, and one of my other computers that prints to that printer, their tray 3 says Not Available. Can someone please tell me how I can fix that, so they can print to the 3rd tray. I know I have recently done this on another computer for a Network HP 4050 printer, but I don't remember what I did, I just kind of happened upon the fix. Thanks.
