  Paper tray selection on HP printers? 
 The Question is:
 
I have a HP8000 . What are the possible reasons that I cannot print to tray
4 in this printer. It shows up in properties and is plugged in.
Thanks
 
 
 The Answer is:
 
  There is not enough information here to provide a specific answer.
 
  First, verify that the printer is operating correctly.  Ensure that
  all paper trays are positioned correctly, and particularly ensure that
  the microswitch is correctly engaged for paper tray 4.  (Failure to
  correctly engage the microswitch found near the paper tray(s) on most
  printers can cause a printer to not detect the paper tray, to require
  manually feeding the paper, or various other misbehaviour.)
 
  For assistance with the operations of an HP printer, and to check that
  the HP printer firmware is current, please contact your hardware support
  organization or contact HP support directly.  (The HP LaserJet 8000
  series printer usually requires firmware "19980610 MB4.28" or later,
  check with HP for details.)
 
  If the printer is operating correctly and the problem persists (and thus
  the problem appears to be related to software or communications), please
  contact the Compaq Customer Support Center -- expect to be asked for
  information on the software you are using to connect to and print to
  the printer, as well as how you are attempting to select the paper
  tray, etc.
