Thanks to Michael Kairys for this information. Ever since the release of NT 4.0, Hewlett Packard DeskJet users have complained about the lack of drivers that match the features of their Windows 95 equivalents.
For example, the DeskJet 870 Windows 95 drivers, written by HP, use HP's proprietary C-Ret color enhancement technology and include utilities for maintaining the printer, but the Windows NT drivers (supplied by Microsoft) provide inferior print quality and no utilities. The DeskJet 820, a "Windows Printing System" printer, which uses the CPU to prepare the page images prior to printing, has never gotten an NT.
Well, Hewlett Packard has finally made their own driver for the 870 printers. You can find more information about all of HP's 800-series printers at http://www.hp.com/cposupport/indexes1/dj8ser.html. The 870 page in particular can be found at http://www.hp.com/cposupport/indexes1/dj870cxs.html.
Supposedly, HP is developing an 820 driver for NT as well
