Methods and systems for operating a printing apparatus
Various embodiments illustrated herein disclose a method comprising rendering a buffer image from a first image data received for printing. Further, the method includes scaling the buffer image to generated scaled buffer image. Furthermore, the method includes determining a first location of a machine readable indicia in the scaled buffer image. Additionally, the method includes causing a print head to print the buffer image on a print media to generate a printed content.
1. A method for operating a user computing device, the method comprising:
determining, by a processor, a first location of a machine readable indicia in a first image;
converting, by the processor, the first image to a bit stream;
transmitting, by the processor, an instruction to a printing apparatus to print on a print media to generate printed content, wherein the instruction comprises the bit stream and the first location of the machine readable indicia; and
causing, by the processor, an image sensor to capture a second image of a portion of the printed content based on the first location of the machine readable indicia, wherein the portion of the printed content is at a second location in the printed content, and wherein the second location in the printed content corresponds to the first location of the machine readable indicia in the first image, and wherein prior to causing the image sensor to capture the second image of the portion of the printed content, the processor is configured to align the portion of the printed content with the image sensor based on distances between a print head of the printing apparatus, the image sensor, and the second location in the printed content.

9. The method of claim 1 , wherein the image sensor comprises a contact image sensor and wherein the image sensor is in communication with a print head of the printing apparatus.
10. The method of claim 1 , wherein the image sensor is attached to the printing apparatus.
11. A printing apparatus comprising:
a print head configured to print a first image on print media;
an image sensor configured to capture a second image; and
a processor communicatively coupled to the print head and the image sensor, wherein the processor is configured to:
determine a first location of a machine readable indicia in the first image,
convert the first image to a bit stream;
cause the bit stream to be printed via the print head to generate printed content on the print media;
determine a second location of the machine readable indicia in the printed content based on the first location of the machine readable indicia in the first image, and
cause the image sensor to capture the second image of the portion of the printed content based on the second location of the machine readable indicia, wherein prior to causing the image sensor to capture the second image of the portion of the printed content, the processor is configured to align the portion of the printed content with the image sensor based on distances between the print head, the image sensor, and the second location of the machine readable indicia in the printed content.
12. The printing apparatus of claim 11 , wherein the processor is further configured to scale the first image to generate a scaled first image.
13. The printing apparatus of claim 11 , wherein the portion of the printed content comprises the machine readable indicia, and wherein the processor is configured to grade the machine readable indicia in the second image.
14. The printing apparatus of claim 12 , wherein the first image is scaled based on a scale ratio.
15. The printing apparatus of claim 12 , wherein first location of the machine readable indicia is determined in the scaled first image.
16. The printing apparatus of claim 12 , wherein the processor is further configured to:
retrieve a portion of the second image based on the first location of the machine readable indicia in the scaled first image, wherein the portion of the second image includes the machine readable indicia; and
grade the machine readable indicia in the portion of the second image.
17. The printing apparatus of claim 11 , wherein the image sensor comprises a contact image sensor.
18. The printing apparatus of claim 12 , wherein the second location in the printed content is determined based on at least a scale ratio and/or one or more mechanical parameters.
19. A system comprising:
a printing apparatus comprising:
a print head configured to print a first image on print media to generate a printed content; and
an image sensor configured to capture a second image of a portion of the printed content; and
