Our CIO has tasked us with determining a way to default all of our printer drivers to black and white printing. The user would be able to select color on a per job basis but would not be able to permanently change the DEFAULT to color. Currently, the user could go into the printer preferences and uncheck the "print in greyscale" option. I am just trying to get some suggestions on the best way to handle this. We have not been able to figure out how to modify the driver directly to achieve this. We are using all HP printers. Any suggestions would be appreciated.
