I do not doubt that the above methods can be done. Try is this way:

Share the printer. Through the net use to designate the port LPT1 or LPT2, and it is possible and 3 previous printer.

I know that this method works when you print from DOS on the monochrome laser printers do not have LPT or connector is not connected (used on HP LJ 2300 and HP LJ P3005n). But HP DeskJet 3940 fails. The document in turn rises, but there is an error. I would like to try on the HP Color LJ 1600 and HP Color LJ CP1215 (preferably the 2nd).
