Abstract

A printer-verifier system for providing print quality feedback and controlling print quality is provided. The printer-verifier system may include a printing mechanism configured to print a machine-readable indicia on a print media; a verifier device configured to optically scan the machine-readable indicia; and a print quality monitoring device in electronic communication with the printing mechanism and the verifier device.

Claims

1. A printer verification device comprising:

a sensing device configured to optically sense an image printed onto print media within a printer;

a quality analyzing device configured to analyze the print quality of the image printed onto the print media; and

a printer control device configured to;

instruct a printing mechanism to print diagnostic information onto the print media in response to a determination by the quality analyzing device that the print quality does not meet predetermined quality standards, wherein the diagnostic information includes maintenance instructions defining an appropriate course of at least one corrective action, wherein the at least one corrective action includes changing a pressure that a printhead of the printing mechanism applies to the print media, changing temperature of the printhead, cleaning the printhead, repairing the printhead, replacing the printhead, realigning the print media within the printer, and/or realigning a printer ribbon within the printer.

2. The printer verification device of claim 1, wherein the diagnostic information includes gray levels, American National Standards Institute (ANSI) grade levels, numeric ANSI grades, and/or bar width growth amounts.

3. The printer verification device of claim 2, wherein the quality analyzing device is configured to utilize the diagnostic information to detect errors in the print quality.

4. The printer verification device of claim 1, wherein the print media includes at least one label and the image printed on the label includes at least one barcode.

5. The printer verification device of claim 1, wherein, in response to the quality analyzing device determining that the print quality does not meet the predetermined quality standards, the printer control device instructs the printing mechanism to print the diagnostic information over the image printed onto print media.

6. The printer verification device of claim 1, wherein the printer control device is configured to determine the at least one user action based on association data that associates different print quality errors with respective prescribed corrective actions.

7. A printer comprising:

a printing mechanism configured to print images onto print media; and

a print verification device configured to monitor the print quality of the images printed onto the print media;

wherein the print verification device is configured to analyze the print quality to determine if the print quality meets predetermined quality standards; and

wherein, in response to the print verification device determining that the print quality does not meet the predetermined quality standards, the print verification device instructs the printing mechanism to print diagnostic information onto the print media, wherein the diagnostic information includes maintenance instructions defining at least one user action needed to improve or correct the print quality.

8. The printer of claim 7, wherein the printing mechanism is configured to print the diagnostic information onto the print media.

9. The printer of claim 8, wherein the diagnostic information includes information regarding a level of print quality.

10. The printer of claim 8, wherein the diagnostic information includes gray levels, American National Standards Institute (ANSI) grade levels, numeric ANSI grades, and/or bar width growth amounts.

11. The printer of claim 10, wherein the print verification device is configured to utilize the diagnostic information to detect errors in the print quality.

12. The printer of claim 7, wherein the at least one user action includes changing a pressure that a printhead of the printing mechanism applies to the print media, reducing the temperature of the printhead when the bar width growth is greater than a predetermined percentage, increasing temperature of the printhead when the bar width growth is less than a predetermined percentage, cleaning the printhead when a defects grade failure is determined, repairing or replacing the printhead when a dot failure exceeds a predetermined threshold, realigning the print media within the printer, and/or realigning a printer ribbon within the printer.

13. The printer of claim 7, wherein the print media includes at least one label.

14. The printer of claim 7, wherein the images include at least one barcode.

15. The printer of claim 14, wherein, in response to the print verification device determining that the print quality does not meet the predetermined quality standards, the printing mechanism is configured to print the diagnostic information over the at least one barcode.

16. A method associated with a printer, the method comprising the steps of:

analyzing the print quality of a barcode printed by a printing mechanism onto a label;

determining if the print quality meets predetermined quality standards; and

instructing the printing mechanism to print diagnostic information onto the label in response to the print quality not meeting the predetermined quality standards, wherein the diagnostic information includes maintenance instructions defining at least one user action needed to improve or correct the print quality.

17. The method of claim 16, wherein the diagnostic information includes information regarding a level of print quality.

18. The method of claim 17, wherein the diagnostic information includes gray levels, American National Standards Institute (ANSI) grade levels, numeric ANSI grades, and/or bar width growth amounts.

19. The method of claim 16, wherein the at least one user action is determined based on association data that associates different print quality errors with respective prescribed corrective actions.
