Abstract: A printer is shown which employs an improved data entry technique wherein a predetermined set up time is established for entering semi-fixed information, that is, information which changes but relatively infrequently. A bit map image of the semi-fixed information is created only once after the printer is initialized so that only a bit map image of variable information need be created each time the printer is operated to print. The printer further includes a limited keyboard for the generation of control signals to which the printer's processor responds differently depending upon the mode of operation of the printer. In one mode of operation, the printer's processor is responsive to the actuation of one key to control a display and the entry of data into a memory for printing. In a second mode of operation, however, the printer's processor is responsive to the actuation of that same key to control the movement of paper stock with respect to a print head.
