I don't know how to set your printer to grayscale, but I know you can grayscale things in Microsoft Paint.
EDIT well, here's a review that says you can, "The Epson Stylus Photo R220 costs just $99, but it omits many of the features ... The grayscale test had a slight greenish tint, but showed plenty of detail." Reccommend checking all the tabs and the 'advanced button' window.
