We have a teacher lounch at the school. We have 3 printers in that louch. Color, a black and white, and poster printer. I would like to set the print black and white to be the default printer on all 7 computers in the lounch. The problem is no matter what i tried, it changes for deferent user. Everyone has a roaming profile, but i use the gaprint command to install the printers on those computers. Teachers keep using the poster printer, over and over which keep wasting paper. Is there any way to force a printer to be the default for anyone that is using any of those computers.
