METHOD, DEVICE, AND SYSTEM FOR DIAGNOSING PRINTER PROBLEM BY EVALUATING EMBEDDED DATA IN PRINTED IMAGE, AND COMPUTER-READABLE MEDIUM

摘要

PROBLEM TO BE SOLVED: To provide a method and a system for diagnosing problems of a printer by evaluating embedded data in a print image. SOLUTION: The method triggers a printer to initiate an embedding algorithm and receive the print data, read the printer configuration data, encode the configuration data, insert the configuration data into the print data; send the print data to a print head; and print the data. The printed data is then scanned, run through analysis software, and the embedded data is returned. The embedded data can then be used to diagnose the printer problems or as a digital notary.
