Open the start menu and select Control Panel > Administrative Tools > and choose the Services icon. Locate the Print Spooler service and right-click. Then select the option to “Stop” the service.
Right-click the printer that you want to use, and then click Printing preferences. Make your choices, and then click OK. Under option Print color select color , then the OK button. Now the printer is set to print in color.
First, check your printer settings on the file or picture your trying to print. If your page is setup to print in “grayscale” it will only print in black and white. Change the setting to “default” so it will print in color. If your settings look good from the start, the cartridge may just need to be primed.
Clean the printheads: Sometimes the issue why you are unable to print in color is because our printheads are clogged with ink. Clean the printheads and then print a document to check if color printing works. Some printers also have in-built programs that can clean themselves so remember to check for that.

My 2550n Color LaserJet does not want to print in color
ANSWER : That model had issues with the carousel solenoid sticking. That might explain why it works after you let it sit for 10 minutes. The solenoid gets hotter with use which causes the deteriorated foam on it to become sticky and hold down the release plate instead of letting it go. This allows the carousel to spin when it is supposed to stop for each color. The solenoid is located on the right side of the printer. If you open the lid, it is just behind the opening at the top right. You need to remove the top of the printer and scrape off the goo on top of the solenoid body. I put a piece of thin sticky backed felt to replace it. Other people use electrical tape.
