A semiautomatic electronic printer comprises a housing (2) and, internally, a print head (8). A push-button (3), projecting upwards from the housing (2), is rigidly connected to a frame (7), which is mounted in a spring-charged relationship inside the housing (2) in such a manner to be vertically movable between a rest position and a working one. The frame (7) sustains in the upper part a printed circuit board including a microprocessor for acquiring from a separate computer data that have to be printed, and for storing such data, as well as for controlling the operation of the print head (8), supported by a carriage (20), with its inferior part being brought to touch the medium to be printed when the push-button is pushed downwards and to translate horizontally after the printing of a line of dots until a desired imaging made of a dot matrix has been printed on the all printing surface. |
