This is a known incompatibility between Adobe Photoshop and Hewlett-Packard printers. Essentially, images cannot be directly printed from Photoshop. To work around the problem:

* Scan or create your image in Photoshop.
* Save the image as a jpeg, gif, or other image format.
* Open the image with Picture Viewer. (Found under the Applications folder, or in Apple Menu -> Applications)
* Print the image with Picture Viewer.
