ABSTRACT:
Method and apparatus for altering the length of time a print head in a dot-matrix type of printer mechanism receives driving voltage in accordance with the type of recording media being used by the printer, and preselected print head driving modes selected as a result of control commands provided by a host computer. The print head driving voltage is also measured and digitized, and then used along with the paper type as a parameter for altering the print mode. Memory elements can be used to establish print mode, print media, and drive voltage relationships for automatically selecting an optimum driving time interval in response to one of the selected parameters.
