The Sprocket is rechargeable through a Micro USB, connects to your phone through Bluetooth, and requires Zink / HP photo paper to work. Finally, for the most fun a printer can provide, considering the HP Sprocket 2-in-1 camera printer that combines the convenience of a camera with a built-in printer. And if I can miraculously get the program to execute its basic functions, the printer suddenly decides it will simply not print more than half a page, or worse, that it will cease to remember how to wirelessly connect to the computer in the first place. Instantly print high-quality photos on waterproof, smudge-proof, and sticky-backed Zink paper with no ink or toner needed. It's pocket-size and light weight, combined with a rechargeable battery and interior paper holder, make it remarkably portable.

This is very easy - the top of the printer is secured by magnets, so comes off without any fiddly catches to deal with or break. The HP Sprocket printer paper is available in a unique format that lets you use them as normal, or peel the back away to reveal a sticker design. Put your standard HP Sprocket-sized photos in each of the segments for a look you can change anytime.HP Sprocket Plus prints on paper unique to that model, and each sheet is 30% larger than the photo paper of the HP Sprocket 200 printer. At 50p per sheet, the cost of printing will soon add up, and that remains the biggest drawback of Zink printers. This version of Windows running with the processor or chipsets used in this system has limited support from Microsoft.

The Sprocket is actually even more portable than an Instax (it’s shaped like a smaller, stouter iPhone), though I usually just print pictures — my cat snoozing on the sofa, a homemade bowl of pasta, nail art from my most recent manicure — right at home. It can pull photos from your camera roll, Instagram, Flickr, or Facebook account, and because it also has access to your camera, you can take a photo of whatever you want to print. Little things like the magnet catches on the top mean it's unlikely to get damaged by the wear and tear of repeatedly loading paper.One potential problem I did come across while printing is that you need to be careful with how many images you send to the printer at a time, and to make sure you remove each sheet as soon as it's finished printing. There's a very brief quick start guide in the box, which directs users to install the HP Sprocket app and follow the app's instructions.
