Abstract

A method and apparatus are provided for adaptively controlling printer functions of a dot matrix printer in response to sensing the type of printer ink cartridge being used. An identifying resistive value is applied to surface of the cartridge and installed within the printer. The printer includes contacts that include sensors and sensor circuitry useful to detect a presence of the resistive indicator and the resistive value thereof. The sensed resistive value is used to directly control printer functions, and/or to access stored data or printer control routines specific to the type of cartridge, or desired performance characteristics. Stored information, which may be appended by other sensed information such as printer usage data, is used to selectively regulate printer operation to achieve maximum efficiency and performance from the particular ink cartridge.
