Choose one of your pages that has a fair number of colors and images, and create a print-friendly style sheet for it. Be sure to add an extra <link /> tag to the page that links in the print-specific style sheet.
If you're feeling really ambitious, try using the handheld value of the <link /> tag's media attribute to create a handheld-specific version of one of your web pages. The concept is the same as creating a print-friendly page, except in this case you're dealing with an extremely constrained screen size instead of a printed page. You can test the page by publishing it and then opening it using a mobile phone or handheld computer browser.
