PRINTER HAVING IDENTIFIABLE INTERCHANGEABLE RECORDING HEADS OR PENS

摘要

A dot-matrix printer is provided with different types of recording heads or pens which are interchangeably attachable to the printer carriage. The pens are provided with individual codes which are read by the printer control system and used to reconfigure its control function to suit the control requirements of the identified head. Such a system may include a microprocessor responsive to individual sets of instructions or programs providing new and different processing capabilities for printing control in response to the insertion of a new recording head or pen.
