ABSTRACT:
A method triggers a printer (106) to receive a trigger to initiate an embedding algorithm (220), receive the print data (228); read the printer configuration data (230); encode the configuration data (230); insert the configuration data (230) into the print data (228); send the print data (228) to a printhead (206); 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 printer problems or as a digital notary.
