Print device, print quality judgement method, and non-transitory computer-readable storage medium

A print quality judgment method performed by a processor of a print device, the method comprising:

• an acquisition process of acquiring data, of a judgment image, that does not satisfy a predetermined standard used to judge a print quality of a barcode printed by the print device, the print device including a housing, a print head, a conveyance portion, and an image reader, the housing including a supply space, the supply space being configured to accommodate a medium, the print head being configured to print an image on the medium fed out from the supply space, the conveyance portion, including a motor, being configured to convey the medium in a conveyance direction from the supply space toward the print head, and the image reader being configured to read the image printed by the print head and to output read image data to the processor;
• a print process of controlling the print head, based on the data of the judgment image, to print the judgment image on the medium;
• a judgment process of judging whether read judgment image data output by the image reader as a result of reading the judgment image satisfies the predetermined standard;
• and
• a notification process of performing an error notification, when, in the judgment process, it is judged that the read judgment image data satisfies the predetermined standard.

A non-transitory computer-readable storage medium storing computer-readable instructions that are executed by a processor of a print device, the computer-readable instructions performing processes comprising:

• acquisition processing of acquiring data, of a judgment image, that does not satisfy a predetermined standard used to judge a print quality of a barcode printed by the print device, the print device including a housing, a print head, a conveyance portion, and an image reader, the housing including a supply space, the supply space being configured to accommodate a medium, the print head being configured to print an image on the medium fed out from the supply space, the conveyance portion, including a motor, being configured to convey the medium in a conveyance direction from the supply space toward the print head, and the reader being configured to read the image printed by the print head and to output read image data to the processor;
• print processing of controlling the print head, based on the data of the judgment image, to print a judgment image on the medium;
• judgment processing of judging whether read judgment image data output by the image reader as a result of reading the judgment image satisfies the predetermined standard;
• and
• notification processing of performing an error notification, when, in the judgment processing, it is judged that the read judgment image data satisfies the predetermined standard.
