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 comprising:
rendering, by a processor, a buffer image from a first image data received for printing;
scaling, by the processor, the buffer image to generate a scaled buffer image, wherein the buffer image is scaled based on a scale ratio;
determining, by the processor, a first location of a machine readable indicia in the scaled buffer image;
causing, by the processor, a print head to print the buffer image on a print media to generate a printed content; and
causing, by the processor, an image capturing unit 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 is determined based on the scale ratio and corresponds to the first location of the machine readable indicia in the scaled buffer image.
2. The method of claim 1 , wherein the portion of the printed content includes the machine readable indicia.
3. The method of claim 2 further comprising grading, by the processor, the machine readable indicia in the second image, wherein the grading of the machine readable indicia in the second image is indicative of the grading of the machine readable indicia in the printed content.
4. The method of claim 1 further comprising:
causing, by the processor, an image capturing unit to capture a second image of the printed content;
retrieving, by the processor, a portion of the second image based on the first location of the machine readable indicia in the scaled buffer image, wherein the portion of the second image includes the machine readable indicia; and
grading, by the processor, the machine readable indicia in the portion of the second image.
5. The method of claim 1 further comprising receiving, by the processor, the first image data as a binary bit stream.
6. The method of claim 1 , wherein the machine readable indicia is determined prior to causing the print head to print the buffer image.
7. A printing apparatus comprising:
a print head configured to print a buffer image on print media to generate a printed content;
an image capturing unit configured to capture a second image of a portion of the printed content; and
a processor communicatively coupled to the print head and the image capturing unit, wherein the processor is configured to:
scale the buffer image to generate scaled buffer image, wherein the buffer image is scaled based on a scale ratio;
determine a first location of a machine readable indicia in the scaled buffer image,
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 scaled buffer image and the scale ratio, and
cause the image capturing unit to capture the second image of the portion of the printed content based on the second location of the machine readable indicia.
8. The printing apparatus of claim 7 , wherein the processor is configured to receive a first image data, and render the buffer image from the first image data.
9. The printing apparatus of claim 7 , 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, wherein the grading of the machine readable indicia in the second image is indicative of the grading of the machine readable indicia in the printed content.
10. The printing apparatus of claim 7 , wherein an area of the scaled buffer image is less than an area of the buffer image.
