PRINTER HEAD, PRINTER, PRINTER SYSTEM, DATA PROCESSOR AND METHOD FOR PROCESSING DATA

摘要

PROBLEM TO BE SOLVED: To prevent illegal printing of data or the like protected by the copyright. SOLUTION: When security data is detected by a data detecting means 15 from print data externally input to a data input means 11, a print output of a print executing means 17 is controlled in operation to a predetermined state by an operation control means 18. For example, if print inhibit is set as the operation control corresponding to the security data and the security data is inserted to image data not allowed for printing by the copyright or the like, even if the image data is data transmitted as the print data from a data processor 200 to a printer 300, no print output is conducted. Since the operation control is executed in a printer head 400 difficult to be analyzed in an internal process, illegal printing or the like can be satisfactorily prevent.
