Where the RJ-3050Ai fits

The RJ-3050Ai sits in Brother's RJ family and is grouped here as a mobile, 2-, 3- or 4-inch label printer. It is cataloged as a direct-thermal model, so the intended configuration prints on heat-sensitive media without a transfer ribbon.

Cataloged resolution options are 203 dpi. A specific orderable unit may support only one of those values, and label templates expressed in dots must match the installed printhead. Use this page to build a shortlist, then compare the exact regional specification, interfaces, options and supported supplies with the manufacturer before purchase.
