You'll want to assess the connectivity options. If you want a hassle-free printing experience, use a portable printer that offers wireless connectivity and support for protocols like Apple AirPrint.

We've tested hundreds of printers for home, office, and studio. This includes the best all-in-one printers, best label printers, and the best small business printers. The most common method of printing from your iPhone is by using AirPrint. For AirPrint to work, both your phone and portable printer must be on the same Wi-Fi network. You can print from Mail, Photos, or Safari using the "Share" feature, which should populate "Print" as an option.Some portable printers support Bluetooth connections, which you can set up by going into your iPhone's "Settings" and "Bluetooth." Tape the Bluetooth switch to "On" and make the printer discoverable by following its included directions. When the printer name appears on your iPhone, tap it to connect. Printing is performed the same way as it was over Wi-Fi. Why is my printer offline? Besides supporting print via Wi-Fi and USB the PRO-100S also can print directly from cloud-based and online photo storage services such Facebook, Dropbox, Google Drive and OneDrive via PIXMA Cloud Link. What should you expect from your portable printer? How about reliability, transportability, and clear text, all of which the Canon Pixma TR150 delivers? Canon fits the most important features of a printer into this small device, which measures 7.3 x 12.7 x 2.6 inches, weighs only 4.6 lbs, and features a 1.44-inch OLED display. What differentiates this model from most portable printers is the addition of MFi (Made For iPhone), making it easier to sync with Mac and iOS devices over Bluetooth. With a battery that lasts for 100 prints and no ink limitations, you really can print from anywhere with this rugged and highly portable device.You can connect the printer to computers and smartphones through USB or Bluetooth, but since there's no Wi-Fi connectivity, you can't use Apple AirPrint, Google Cloud Print, Mopria, and other connection that rely on Wi-Fi.

Canon first released the Pro model in 2012, designed specifically for printing high-quality photos. It achieves this through an 8-ink dye based system which results in professional quality prints. There may be limitations on just how small you can go, though. Portable printers and scanners will likely occupy more room than a standard portable printer. Of course, the function of the printer will matter most. If you need a standard printer, you don't want to look at label or photo printers. Consider the functions you need to make sure you're getting the most out of your next portable printer. Will you need to print in color, or does a monochromatic option work? Does your printing require special paper or even a specific type of ink? How about connectivity, specifically to mobile devices? Is Bluetooth enough, or do you need a Wi-Fi-enabled printer? If you have a very small home or office setup, this also may not be the printer for you. At 52 lb (24kg), it probably would take two people to install it and move it around if necessary. When testing print quality, we always print the same test documents for an accurate overview across all printers. This document includes text in different font sizes and colors, as well as images. We also test patterns, evaluating sharpness and color fidelity.
