ABSTRACT:
Basic elements of a modular printer system may comprise a rectangular open frame with receptacles for a printer module and computerized terminal module, and with an external configuration for receiving modular components such as a carrying handle, a support foot, an auxiliary terminal module mounting bracket and an AC adaptor module. Respective different paper tray modules may be selectively secured to the open frame to form a bottom closure and to provide a repository for appropriate circuit boards and an on-board battery if needed, as well as containing an appropriate supply of paper for the printer (e.g. 50 sheets or 200 sheets). Respective terminal adaptor modules may secure different generations of computerized terminals in the frame for data transfer to the printer. A terminal module may utilize a spring-urged retainer for retaining a hand-held computerized terminal therewith. Respective printer modules may adapt different printer models to the frame, and each such printer module may be reversible in the frame to accommodate different applications, e.g. as a portable unit, and as a van-mounted unit with in-board, out-board and/or remote mounting of terminal modules.
