software conflits--Drivers for HP printe

Has anyone or is anyone having problems getting hp deskjet prints to print correctly on systemshared printers with the PC's running win2000? WE never seemed to have this problem with win98 however now with 2000 we have had two cases where the envelopes are not feeding in to the printer far enough to print in the correct address location on the envelope. We have tryed resetting ever setting we know of or can locate but nothing seems to work. All other print jobs seem to be working correctly.anyone have any ideas..?? Already tried downloading the latest drivers...
