Conclusion: If all you want to do is print photos on your desk at home or in the office, though, this model isn't a cost-efficient pick. You would be better off buying an inexpensive inkjet printer. Your printed photos would cost less, possibly last longer, and even look a little better.
Pros: Sharp photo prints, Lightweight, with optional battery for true portable use, Wi-Fi support, Big LCD for a tiny printer, Supports printing from iOS
Cons: High per-print costs, No Wi-Fi Direct support, Battery/charger option is pricey
Excerpt: Dedicated photo printers like the Canon Selphy CP900 have become something of a niche product. If you need a portable, dedicated 4x6 photo printer, that makes the CP900 one of your few options.
Summary: Canon's latest ultra-compact thermal dye photo printer has a welcome upgrade of Wi-Fi over its predecessor alongside good quality images, simple controls and flash drive/SD card instant processing.
Excerpt: While an inkjet might seem like the obvious choice for printing photos at home, it's not the only one. The Selphy CP900 is the latest in Canon's range of dye-sublimation photo printers. It comes with a large colour screen, a memory card slot and support for wireless networking.
