Title
(EN) CAPTURED IMAGE BASED VALIDATION OF PRINTED TOKENS
(FR) VALIDATION FONDÉE SUR UNE IMAGE CAPTURÉE DE JETONS IMPRIMÉS
Abstract
(EN)
According to examples, an apparatus may include a processor and a non-transitory computer readable medium that the processor may execute to determine whether a token is to be printed onto a medium and based on a determination that the token is to be printed onto the medium, following printing onto the medium in a printing system, cause a scan bar in a media feed path of the printing system to capture an image of the printed medium. The processor may also determine, from the captured image of the printed medium, whether the token was properly printed onto the printed medium and, based on a determination that the token was not properly printed onto the printed medium, output an indication and/or an instruction corresponding to the token being improperly printed.
(FR)
Des exemples de l'invention concernent un appareil pouvant comprendre un processeur et un support lisible par ordinateur non transitoire que le processeur peut exécuter afin de déterminer si un jeton doit être imprimé sur un support et en fonction d'une détermination que le jeton doit être imprimé sur le support, après l'impression sur le support dans un système d'impression, provoquer la capture, par une barre de balayage dans un trajet d'alimentation de support du système d'impression, d'une image du support imprimé. Le processeur peut également déterminer, à partir de l'image capturée du support imprimé, si le jeton a été correctement imprimé sur le support imprimé et, en fonction d'une détermination que le jeton n'a pas été correctement imprimé sur le support imprimé, émettre en sortie une indication et/ou une instruction correspondant à l'impression incorrecte du jeton.
