The 82242A Infrared Printing Module for the HP-41 is not bi-directional. It is able to transmit only. It was designed to work exclusively with the HP82240A (&B) printer, which is receive only. The module contains all of the printing functions of the standard HP-41 printers (HP82143, HP82162 / -IL) and some additional functions necessary for the implementation of the remote printer link. From other posts on this forum, it sounds like HP designed an application card for the HP-48 that would capture printed output from the HP-41, and others seem to have designed custom devices to do so for a PC.
