Abstract
A parametric programmable thermal printer is disclosed. The printer may include a controller that performs functions such as thermal history control and common mode voltage correction. The controller may be implemented in an integrated programmable medium such as a Field-Programmable Gate Array (FPGA). Functions performed by the controller may be parameterized, and parameter values may be stored in registers. The controller may be used with a different thermal printer by changing the parameter values and/or reprogramming the programmable medium, and without otherwise redesigning or remanufacturing the controller.
Claims2
1:
- A thermal printer controller comprising an integrated circuit, the integrated circuit comprising:
- a first thermal history control engine to receive first print data and to perform thermal history control on the first print data to produce second print data;
- a first common mode voltage correction engine to receive the second print data and to perform common mode voltage correction on the second print data to produce third print data;
- and
- an output processor to provide the third print data to a first thermal print head.
