I have two 8600 printers hooked wirelessly to my pc. The original which works fine I'll refer to as, "Two trays." The 2nd I'll refer to as, "one tray. Both printer use the same driver per hp. When I open the hp printer app for 2 tray I get the full menu of options. When I open the app for 1 tray I get a limited set of options. Also for some reason when I print photos on 1 tray they have a green overcast.
