I have HP Color laserjet 2320 MFP printer and need to setup a print driver that only prints black and white. I tried using the hp universal driver but that printed in color. I tried setting up the printing preferences in the server to grey scale but that did not trickle down to the clients. i tried a laserjet 4100 driver which is only black and white but the paper margins got goofed up. anyone have any advice or ideas.
