The print substrate support (3) and longitudinal guides (4) for a print-head slider (7) are disposed in parallel at the invention printer. A controllable paper-guide drive motor (10) is furnished for the paper guide (9; 9a) and a drive motor (11) is furnished for the print-head slider (7). In order to be able to economically produce printers for different paper widths, and in order to eliminate problems of interfering radiation, a separated space (14) is furnished at the end of the paper guide (9; 9a) or respectively, of the longitudinal guide (4). At least one control-logic printed circuit board (15), an interface printed circuit board (16), the paper-guide drive motor (10) as well as the print-head-slider drive motor (11) are disposed in the separated enclosed space (14).

Printer, in particular matrix pin printer

A matrix printer, having a movable print head, a paper feed and advance mechanism and an ink ribbon system, is driven by two motors; one for the print head and one for paper feeding and ribbon movement. This second motor is a reversible one and drives the paper advance when rotating in one direction and the ink ribbon when rotating in the opposite direction. Speed control for the paper feed phase is derived from a cam on the input shaft for the paper advance. A reset mechanism for that shaft is also included.
