  • Systems and methods for barcode verification
    Patent number: 10867145
    Abstract: 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.
