1. WO2020117243 - CAPTURED IMAGE BASED VALIDATION OF PRINTED TOKENS

Note: Text based on automatic Optical Character Recognition processes. Please use the PDF version for legal matters

[ EN ]

What is claimed is:

1. An apparatus comprising:

a processor; and

a non-transitory computer readable medium on which is stored instructions that when executed by the processor, are to cause the processor to:

determine whether a token is to be printed onto a medium;

based on a determination that the token is to be printed onto the medium, following printing onto the medium in a printing system, cause a scan bar in a media feed path of the printing system to capture an image of the printed medium;

determine, from the captured image of the printed medium, whether the token was properly printed onto the printed medium; and

based on a determination that the token was not properly printed onto the printed medium, output an indication and/or an instruction corresponding to the token being improperly printed.

2. The apparatus of claim 1 , wherein the instructions are further to cause the processor to:

based on a determination that the token is not to be printed onto the medium, maintain the scan bar in an inactive state as the printed medium is fed in the media feed path past the scan bar.

3. The apparatus of claim 1 , wherein the printing system comprises a second media feed path, wherein the scan bar does not access the second media feed path, and wherein the instructions are further to cause the processor to:

based on a determination that the token is not to be printed onto the medium, cause the printed medium to be fed through the second media feed path.

4. The apparatus of claim 1 , wherein the instructions are further to cause the processor to:

access a raster image to be printed onto the medium; and

determine whether the token is to be printed onto the medium from the accessed raster image to be printed onto the medium.

5. The apparatus of claim 1 , wherein the instructions are further to cause the processor to:

send a copy of the captured image of the printed medium, a copy of the token in the captured image, or both, to a computing device that is remote from the apparatus, wherein the computing device is to determine whether the token was properly printed onto the printed medium from the captured image of the printed medium, the copy of the token, or both, and to return an indication as to whether the token was properly printed onto the printed medium to the apparatus; and

wherein the processor is to determine whether the token was properly printed onto the printed medium based on the indication returned from the computing device.

6. The apparatus of claim 5, wherein the instructions are further to cause the processor to:

determine whether a validation of the token is to occur at the apparatus or at the computing device;

send the copy of the captured image of the printed medium, a copy of the token in the captured image, or both, to the computing device based on a determination that the validation of the token is to occur at the computing device; and

perform the validation of the token based on a determination that the validation of the token is to occur at the apparatus.

7. The apparatus of claim 1 , wherein the token includes or represents meta-data, and wherein the instructions are further to cause the processor to: determine whether the token was properly printed onto the printed medium based on whether the token was printed accurately and/or whether the meta-data included in or represented in the token is accurately readable.

8. The apparatus of claim 1 , wherein, to output an indication and/or an instruction corresponding to the token being improperly printed, the instructions are further to cause the processor to:

output a visual indication on a display that the token was improperly printed;

prevent a finishing operation from being performed on the printed medium; prevent a subsequent medium on which the token is to be printed from being printed;

output an alert that the printing system is need of fixing and/or calibration; and/or

modify a setting on the printing system to self-correct the printing of the token.

9. A printing system comprising:

a print mechanism to output a printed medium along a media feed path; a scan bar positioned along the media feed path;

a processor to:

determine that a token is printed onto a medium;

cause the scan bar to capture an image of the printed medium based on a determination that the token is printed onto the medium;

validate, from the captured image of the printed medium, the token; and

based on a determination that the token is invalid, output an indication and/or an instruction corresponding to the token being invalid.

10. The printing system of claim 9, wherein the processor is further to:

determine that the token is not printed onto the medium;

based on a determination that the token is not printed onto the medium, maintain the scan bar in an inactive state as the printed medium is fed in the media feed path past the scan bar; or

cause the printed medium to be fed through a second media feed path, wherein the scan bar does not access the second media feed path.

1 1. The printing system of claim 9, wherein the processor is further to access a raster image to be printed onto the medium and determine whether the token is printed onto the medium from the accessed raster image to be printed onto the medium.

12. The printing system of claim 1 , wherein the processor is further to:

determine whether validation of the token is to occur at the apparatus or at a computing device remote from the apparatus;

based on a determination that the validation of the token is to occur at the computing device, send a copy of the captured image of the printed medium, a copy of the token in the captured image, or both, to the computing device and validate the token based on an indication returned from the computing device; and

based on a determination that the validation of the token is to occur at the apparatus, perform the validation of the token.

13. A method comprising:

controlling, by a processor, a print mechanism to print content and a token onto a medium;

controlling, by the processor, a scan bar to capture an image of the printed content and the printed token on the printed medium;

determining, by the processor, whether the printed medium includes a valid copy of the token; and

outputting, by the processor, an indication and/or an instruction corresponding to the token being invalidly printed onto the printed medium based on a determination that the printed medium does not include a valid copy of the token.

14. The method of claim 13, further comprising:

determining whether token is to be printed onto the medium;

wherein controlling the scan bar further comprises controlling the scan bar to capture the image of the printed data and the token based on a determination that the token is to be printed onto the medium; and

based on a determination that the token is not to be printed onto the medium, prevent the scan bar from capturing the image of the printed data and the token on the printed medium.

15. The method of claim 13, further comprising:

sending a copy of the captured image of the printed data and the printed token or a copy of the printed token in the captured image to a computing device remote from the processor, wherein the computing device is to return an indication as to whether the token was properly printed onto the printed medium to the processor; and

wherein determining whether the printed medium includes a valid copy of the token further comprises determining whether the printed medium includes a valid copy of the token based on the indication received from the computing device.
