The new Brother models are the $449 RJ-2035B with a printing width up to 48mm, and the $649 RJ-3035B which prints up to 72mm wide.

Both have a print resolution of 203dpi and a maximum print speed of 4ips (102mmps), and feature Bluetooth 5 and USB interfaces, support for most printer command languages, and drivers for Windows 7 and later, macOS 10.11 and later, and major Linux distributions.

They are the first Brother printers supporting OPOS and JPOS for easier integration with POS systems, and Brother provides SDKs for Windows, Android and iOS.

Applications include roaming checkouts to speed up shopping, to support click-and-collect transactions, and to help avoid congestion in these days of social distancing; printing parking notices or speeding tickets; and printing picking slips to save warehouse workers having to keep returning to a central location.

Recognising that such devices are often used in harsher conditions than most office equipment, the two RJ series printers are drop tested to 1.8m and are IP42 rated, meaning they can withstand dripping water when tilted but are not dustproof.

Optional accessories include hot-swappable Li-ion batteries, a charging cradle, a one-bay battery charger, a car adaptor, and a shoulder strap (a belt clip comes as standard). For the RJ-3035B (pictured below) there's also a four-bay battery charger and a roll holder allowing the use of narrow media.

"The retail and logistics landscapes are drastically changing, as new measures are regularly put in place during this period, and we anticipate that many of these changes will remain long term. Therefore, the new RJ series comes at a time where our customers are looking to innovate the way they manage their businesses, by sourcing bespoke solutions for all the processes they have to put in place to keep trading efficiently and operating in line with new protocol," said Brother International Australia mobile print and labelling specialist David Molloy.

"Our new affordable mobile printers have been created with our customers in mind, to be compatible, flexible and well connected. In addition, the series has a range of customisation options to fulfil the requirements of different vertical applications, reflecting the needs of those working in the field or in retail. The series is ideal for forward-thinking organisations who need speedy, responsive mobile printing for flexibility and high levels of productivity."

The RJ-2035B and RJ-3035B will be available from 1 September.
