Abstract
The printer control module is programmed to output control signals to the printer driver characterized by the data written in the control registers. The control system for a printing apparatus includes a printer unit responsive to a printer driver unit. The printer driver unit is responsive to the control system. The control system has a programmable printer control module in communication with the printer driver unit and a programmable microcomputer in bus communication with the printer control module. The microcomputer has a non-volatile memory unit for storing the data. The printer driver unit is responsive to control signals from the printer control module for driving the printer unit. The printer control module includes a buffer for holding printer data and the registers of the control module, including a control register, a shift register and a strobe width register. A strobe signal module generates a strobe signal for the printer driver unit having one of a plurality of strobe widths selected in response to the data written in the strobe width register. The control module also selectively causes one of a plurality of clock signals for the printer driver unit in response to d…
