ABSTRACT:
A compact printer having a cylindrical support member and a type carrier member externally affixed to the support member. A type printing assembly is disposed within the type drum for causing characters on the type carrier member to print. A motor for rotating the type drum is connected directly to the drum and disposed immediately adjacent to the type drum with axes of rotation being colinear. A paper feed drive for feeding paper one time per revolution of the type drum includes an intermittent tooth on an end of the support member, a feed gear for being turned by engagement with the intermittent gear, and a paper feed roller driven by the feed gear to feed paper to be printed on. A generating means including a cam on the type drum, positively generates an output indicative of a given position of the type drum.
