A method for tolerance compensation in an ink jet print head reduces the expense for improving print quality. Therefore, despite the reduced expense, tolerances both within a module and from one module to another should be compensated for. Even before a final installation of the ink jet print head in a printing device, after an assessment of test printouts, initially gaps at transitions from one module to another are compensated for mechanically by rotating the ink jet print head and are stored in memory externally. Then individual print data for the ink jet print head are generated electronically and stored in a nonvolatile manner internally in the print head.

In a security module and method for monitoring security in an electronic system, a microprocessor that is interconnected to further function units is programmed for overlapping processing with validation of the system status occurring in the meantime, and drives an indicator for signaling the module status.
