I have read all the posts on the Forum but not found the answer. but I can not print images in the correct size. I can not choose 315 DPI. how do I print Proxis?

You can choose 315 dpi via any image software.
Even IrfanView (free image browsing software) enables you to set DPI via Information (I shortcut).

What I do is paste the images in MS Word, right-click the image, go to Size, and make it 2.49 x 3.48. I think that should be correct.. I get 8 cards to the page if you thin the margins.
