Abstract
A universal controller interface for use in a number of different barcode printers is disposed between the printer's microprocessor and a number of the printer's input and output devices including the printhead. The controller includes a microprocessor interface that allows the controller to be used with various types of printer microprocessors. The controller also includes a printhead control circuit that allows the controller to be used with various types of printheads such as an intelligent thermal printhead or a non-intelligent thermal printhead. The controller also includes a programmable serial input/output port and a programmable baud rate generator so as to further increase its flexibility and use with various types of barcode printer input and output devices. A memory protection circuit of the controller allows various portions of the printer's random access memory to be protected if desired.
