A belated Thanks for your advice but again I have tried everything. I just recently had the need to print a color documentt and no luck. I do not use this printer all that often. I use another device for "draft" printing. The best I can do is to use my older winxp PC to print in color. As for my win7 device-no luck. I have deleted the 8550dt printer and drivers and downloaded new drivers in an attempt to "fix" the problem-no luck. I have had this printer since 8/4/2006 and it has been a great device. Not heaviliy used maybe 256,000 pages in 6 years and only one maintenance kit change. win7 is the problem I guess.
