The RJ-4030 Ruggedjet 4 MCR Kit from Brother takes the convenience of mobile printing to a new level with its 6.0' shock resistant design. In addition to the contents of the standard RJ4030, the RJ4030M-K includes a Li-ion battery and a magnetic card reader. The magnetic card reader provides the ability to swipe cards with magnetic strips (such as credit cards, licenses, and ID cards) rather than having to input the information manually.

The printer supports media up to 4.0" wide, ideal for printing labels and receipts. In addition to printing documents, the RJ4030 can print most barcode formats, convenient for keeping track of invoices, inventory, and other crucial items.
