Capitalizing on people's nostalgia for old Polaroid prints, a company called Breakfast will soon beta-test a location-based printer that will create inkless, on-demand photos from the Instagram iPhone app
. Instaprint, as it's called, automatically prints photos that are taken with Instagram app and tagged with a specific location or hashtag. Next week, Breakfast will show off two printers to SXSW, where conference attendees can use the hashtag #SXSW. If you tag a photo with #instaprint before March 10th, you can watch the photo be printed and posted live on Instaprint's site
. The photos are created with a thermal printing technology called ZINK -- which is also used in modern Polaroid prints --- that doesn't use ink. Aside from real-time printing, your photos will be archived online for your viewing pleasure, as well.
