There is provided an information processing apparatus. A first acquisition unit acquires first information concerning a size of a print region where a barcode is printed. A generation unit generates, based on the first information acquired by the first acquisition unit, image data of the barcode to be printed in the print region. The first information includes width information concerning a width of the print region and height information concerning a height of the print region. The generation unit generates the image data including, as a bar forming the barcode, a bar having a width based on the width information and a height based on the height information.

A method for printing defect detection includes processing and analyzing a difference image obtained by comparing an image scanned with a verifier to a reference image. The detected defects are grouped, and the grouping is refined. Confidence level values are then assigned to the refined groups, and analysis is performed to determine if one or more servicing actions should be taken.

Briefly, a method for verifying the visual perceptibility of a display is provided. An intended message is written to a bistable display. Pixels that comprise portions of the message are measured and evaluated to determine if the message actually displayed on the bistable display was perceptible by a human or a machine. In some cases, information regarding the message actually perceivable from the display may be stored for later use. Responsive to determining that a message is perceivable or not perceivable, alarms may be set, one or more third parties notified, or additional display features may be set.

A system includes a verifier that is operationally integrated with a printer so as to configure one or more elements of the verifier to have a handshake arrangement with one or more elements of the printer when verifying a print quality of a barcode image during printing of the barcode image by the printer. The handshake arrangement can include various unidirectional and/or bidirectional communication signals that are propagated between the verifier and the printer so as to optimize various operational factors such as paper print speed, barcode image verification speed, and barcode verification result intimation. Barcode result intimation can include features such as providing a paper printout indicative of an unacceptable barcode image quality and/or providing a status message upon a display.

A method for evaluating a print quality of a printed document that is printed by a printer is provided. The printer comprises a pre-print image scanner, a post-print image scanner, and a printhead disposed between the pre-print image scanner and the post-print image scanner. The method comprises generating a pre-printing image of a print media, generating the printed document, generating a post-printing image of the printed document, generating a validation image by comparing the post-printing image with the pre-printing image, and comparing the validation image with the source image.
