The CP770 stands out from the crowd in that it is essentially a two-piece printer and bucket set. The plastic bucket fits underneath the printer for storing paper and ink. It also has a built-in handle for carrying the printer on the run. The whole package seems very travel-friendly, but there is a caveat: the printer can't run wirelessly unless you purchase an optional battery pack and Bluetooth adapter, both of which are sold separately.
The body of the printer is a slimmer rectangle with a covered panel that reveals a port for the external paper tray, an IrDA port, and slots for SD, Memory Stick and Compact Flash cards. The proprietary ink cassette fits into a protected bay on the right side of the printer. An external power adapter plugs into the back of the device, but it lacks a rechargeable battery that would make the printer wireless-ready out of the box.
The accompanying bucket is made of durable, moulded plastic and matches the white colour scheme of the printer. It also has a built-in handle as well as two light green tabs that lock onto the printer for safe travel. Inside the bucket, you'll find slots and labels to organise and store the power adapter brick and a few extra paper/ink cassettes. As a whole, the bucket is large enough to accommodate everything you need to take the printer with you.
The control buttons are made from rubber and sit underneath a bright 2.5-inch TFT colour display. The on-screen home menu is easy to read and uses several icons to display the current settings. Picture editing is narrowed down to an image optimiser and five colour presets: Vivid, Neutral, PositiveFilm, Sepia and Black/White. The print settings also let you automatically correct red-eye, insert a date stamp and change the page layout (up to eight images per page).
