Two Brother MPrint MW series mobile printers (an MW-120 and MW-140BT) began printing only blank pages following battery changes and holding the units vertically while printing (the latter in order to coax the paper feed roller into doing its job). While it's not clear which action (if either) was the culprit, the completely undocumented* RESET button on the back of the units resolved the issue.
* Could not find a single reference to it in five different MPrint manuals (in either English or Japanese) nor anywhere else on the Internet.
