Saw your photo booth question in the for sale thread.
I found this website to be the most helpful:
Based on her recommendations I bought two of the same printer she had, the Canon Pixma mini260. I've set them both up and am happy with the test pictures I printed. I bought two 50' rolls of 2" wide peel and stick magnet, which I will cut to size. I get one half, the guest gets the other to take home as their favour.
I'll be selling the two printers and any leftovers I have (buying extra ink and photo paper) after my October 7th (eep! 45 days left) wedding. If you haven't figured out something you like better, I will be putting them up on the for sale thread.
