Problem with HP deskjet 870 drivers and

When the Deskjet 870Cse drivers are loaded on an NT machine with SP6a (Service Pack) Word slows way down. It happens with Office 97 and 2000. I only have to select the DJ870 (Deskjet) as default and things slow down. If I select any other printer asdefault Word is ok.

I have removed and reinstalled the printer and drivers. I have also taken the NT computer down to SP5 and reinstalled the printer and drivers. I still have the same problem. I only have to select the 870 as the default and Word is a slug!
