Aside from HP, few companies have made a bigger commitment to portable or pocket-size photo printers than Kodak. We've already reviewed the company’s Mini 2 Retro Portable Photo Printer and Mini 3 Retro Portable Photo Printer (the latter nabbing an Editors' Choice award) this year, and today it's the Step Slim Instant Mobile Photo Printer's turn. While all three devices create similarly sized images—2 by 3 inches in the Step Slim's case—the two Mini Retros are dye-sublimation (usually called dye-sub) printers.
The Step Slim, though, joins photo printers from Canon, HP, and others in using Zero ink, or Zink, imaging technology. Dye-subs generally churn out slightly nicer prints, while Zink printers are easier to maintain and use. This particular Kodak uses the company's adhesive-backed paper that turns anything you print into a sticker. What's most impressive about the sleek little Slim, however, is its low list price and competitive cost per print, making it a great smartphone companion.
