After installing Phaser 8550 DP PS driver on Windows 7 service pack , I cannot print in color. I noticed that after sending the color pictures to the printer the colors switch to black and white. The same thing happened on all 3 desktops in the office. Can someone help point me figure out how to solve this issue. Many thanks! Allan
Try the Global driver instead, it is 8 years newer and fully supports the printer.
Make sure the issue is all apps, and not just one.
See what happens when Color correction is set to anythiong other than Auto
