Things to consider…
1 Size and weight
> All these printers are smaller than a typical desktop model, but some are particularly small, albeit with some trade-offs in terms of features.
2 Battery life
> Most of the models on test have the option of battery power for use away from mains power. Some of the batteries are integrated and others are an extra.
3 Connectivity
> Wireless connectivity is standard but there are other options ranging from USB to Bluetooth. Some models also create peer-to-peer wireless connections with no need for a router.
4 Print performance
> Your needs may vary from simple black-and-white through to colour photos, and different models have different strengths.
