"You've made your holiday cards with GIMP -- and now you're ready to print them on paper. What's the best way? Should you do it on your own inkjet printer at home, or farm the work out to someone else?
"Get the image ready for printing
"You may remember in the previous article that you sized your image to fit on half of a letter-sized page (A4 if you're outside the US).
"Your image will go on the bottom half of the page, or the right half if you've used a vertical image. In theory, you could do this by setting sizes and offsets in GIMP's print dialog. But that's tricky in practice and it's easy to go wrong. Instead, convert your image to a full page before printing.
"For that, use GIMP's Image->Canvas Size to double the height without changing the width (assuming a horizontal image like my example)."
