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.

Claims

1. A method comprising the steps of:

triggering an embedding algorithm in response to a triggering event;

receiving print data;

reading printer configuration data;

encoding the configuration data;

embedding the encoded configuration data into the print data;

sending the print data to a printhead; and

printing the print data as a visible image comprising the embedded encoded configuration data.

2. The method of claim 1, wherein the triggering step comprises initiating a triggering event via a self-diagnosing algorithm.

3. The method of claim 1, wherein the triggering step comprises initiating a triggering event by activating an alarm by a sensor.

4. The method of claim 1, wherein the triggering step comprises initiating a triggering event by detecting predetermined at least one of keywords and symbols within print data.

5. The method of claim 1, wherein the triggering step comprises initiating a triggering event by detecting the print data originates from a predetermined source.

6. The method of claim 1, wherein the triggering step comprises initiating a triggering event in response to detecting a predetermined time, and wherein the encoded configuration data comprises a time stamp.

7. The method of claim 1, wherein the triggering step comprises initiating a triggering event in response to detecting a predetermined date, and wherein the encoded configuration data comprises a date stamp.

8. The method of claim 1, wherein the triggering step comprises initiating a triggering event by recognizing a set parameter to embed data in the print data.

9. The method of claim 1, wherein the triggering step comprises initiating a triggering event by detecting the activation of a button.

10. The method of claim 9, wherein the activation of the button comprises a detection of activation of a physical button on a printer device.

11. The method of claim 9, wherein the button comprises a “

soft”

button in a software diagnostic application.

12. The method of claim 1, further comprising the steps of:

scanning the printed data to provide scanned data;

analyzing the scanned data to recognize embedded data; and

providing encoded data corresponding to the recognized embedded data.
