Does anyone have any idea on what I may be doing wrong?
Hi Bob,
Nothing really wrong.
Is the card stock actually 9 x 8?
If so, that explains all.
The maximum size the 4880 can print on a 9.0 x 8.0 paper is 8.333 x 7.766
See screen snap attached.
The reason it can print on the plain paper is probably because you allow the plain paper setting to think it is printing to 8.5 x 11 paper.
Try to reduce the size of your image to less than 8.33. It should work fine then.

PS I forgot to mention taht it is easy to do. Just open the print in the page editor, and drag a corner inboard a bit until the dimension changes (upper right) to what you need. Then click OK
