Why We Picked It
The key question for choosing any portable snapshot printer is whether it can print the photo sizes you want. That makes the HP Sprocket 3x4 a good candidate if you want photos up to 3 by 4 inches and no larger. Like most of its competition—including the Kodak Step Instant Mobile Photo Printer, our current top pick for wallet size (2-by-3-inch) photos—the Sprocket 3x4 is small and light, includes a built-in battery, connects without wires (using Bluetooth, in this case), and is reasonably inexpensive.
Who It's For
If the Sprocket 3x4's output is the right size for your needs, and you appreciate that its paper has adhesive on the back (with a peelable backing, so you can stick the photos wherever you like), it could easily be your best choice.
