Abstract
Described is a process for producing information relative to the type of a printer head (18) present in a printer, which head contains at least one printer element (86, 88, 90). The servo component of the printing element (86, 88, 90) has an electrical resistance, which is determined via an electrical evaulation circuit. This resistance is assigned to one of several resistance ranges representing various types of printing head. Depending upon this completed assignment, the evaluation circuit produces a type signal (40a, 40b, 40c) as information. The type signal (40a, 40b, 40c) is made available to a subsequent control, whic can then supply the various types of printing heads (17, 18) with specifically suitable control signals. The invention can be used with practically all types of printing heads, whose printing elements are actuated by electrical or electromechanical servo components and therefore have an electrical resistance.
