Abstract
An improved portable printer apparatus adapted to interface with a handheld computer in either of two alternative ways, including via a connector locating in a receiving well into which the portable computer can be placed or, alternatively, via a radio link. This provides communication flexibility and enhanced reliability. In another feature, electrical power for the printer apparatus is automatically selected from between a power supply, an external battery, and an internal battery, according to a predetermined hierarchy.
