Hey. It sounds like your printer and screen are out of sync. May I ask what program you're printing your images from? The article
http://www.tekserve.com/service/mac-faq/printing/color-doesnt-match.php describes a couple high-level solutions for correcting the problem. If you don't want to try either of those solutions you might try changing the ColorSync profile you use when printing.
To fix ColorSync issues, you can try selecting a different ColorSync profile in your Print dialog box. To do this, open up the program you’re having difficulty with and select Print from the File menu. Make sure the Print window is expanded by clicking the arrow to the right of the Printer drop down menu (you want the triangle to point up). Then go to the drop down menu over the thin horizontal line and select Color Matching. Click the ColorSync radio button and in the Profile drop-down menu select a ColorSync profile. You may have to select Other Profile... and choose from the long list of available profiles to find the one you want. Try looking for a profile with the model name of your printer or the color scheme you are using in your document.
Photoshop users may find that they have to do something different to change their ColorSync settings. In the Photoshop Print dialog (the first box that appears when you select Print from the File menu), select Color Management from the drop down box at the top right of the window. Now you can change the color settings in the box on the right hand side of the Print window. You may have to change the Color Handling drop down menu to Photoshop Manages Colors to access the Printer Profile drop down box.
Additionally, you can use the ColorSync Utility in Macintosh HD/Applications/Utilities/ to manage your ColorSync profiles. If you click the Profiles icon at the top of the utility window you can view your installed ColorSync profiles and decide which one is suitable for the image you are trying to print. If you can’t find a suitable profile, you may have to make one or have one made for you. The article I linked to above suggests two professional-level options for fixing your issue.
