Photosmart C7250 trouble printing 4x6 photos

Question

I can't get the printer to print from the 4x6 photo paper stack when I print from the computer.  It will print from that stack if I bring the photo to the printer using external medium but then it prints it the wrong size.  If I send the print command from the computer it prints the right size but on the full size paper tray.  I created the original to be 3.3x4.8 and it will print that way on plain paper from the lower tray.  If I load the photo on a memory card it will print on the 4x6 paper but will enlarge it to 4x6.
I am using a Macbook Pro OSX 10.5.8 wirelessly to the Photosmart C7250.
