    I never did figure out exactly why HP cautioned against manual switching
  but it probably has something to do with the spike subseptability of the
  interface. I'm sure if you power off the printer you should be safe to 
  turn a manual switch.

    I went the other route and picked up an inexpensive 4-port auto
  switch from CompuAdd. This switch constantly scans the four inputs and
  then locks when a print request comes up. This way you needed worry 
  where you leave the switch positioned and can send files from either 
  computer at your leasure. I beleive the switch ran in the $70 range.
