Adjust these settings until the cards fit comfortably, with the correct number per page, in your browser's Print Preview.
When you're happy with the settings, send all but the first page to your printer, and cut the cards out with something sharp. Either stick the results onto cardboard, slip them into deck-protectors with some spare CCG cards for padding, or just play with them as flimsy bits of paper.
