This is the error that I get trying to install a HP laserjet onto a HP vectra NT4 box on our domain. In particular its a couple of laserjets, 3055 and 1300 models. Our workgroup 4100 installs OK, and a Lexmark Optra does too. But I just can’t get the 3055 & 1300 to setup. I can get all the way thru the wixard when it says that the server doesn’t have a suitable driver, do you want to insatll another? I go yes and point to the CD that came with the printer, specifically the NT4 driver and then I get the driver is unknown error. I successfully fixed this on one NT4 box when the spooler wasn’t interacting with the desktop, but that is not the case on this PC. I even loaded another vectra with a fresh install of NT4, SP6a and updates and I get the same error. Boy it’s bugging me! Can anyone help? Thanks if you can.
