I am using an HP Deskjet 693C printer with Windows NT 4.0. HP's drivers/printer toolbox utilities do not work on NT. I downloaded the limited drivers from Microsoft. They work ok but not great. My main concern is that I cannot install the printer toolbox that allows me to do things like align, clean, and test the print cartridges. Microsoft has not rewritten this portion of code for the printer and there does not seem to be a manual way of performing these tasks. Does anyone know how I might obtain new or install the existing utilites for the Deskjet? I can't believe that HP has not addressed this issue!
