  • Patent number: 11214083
    Abstract: In one example in accordance with the present disclosure, a printing system is described. The printing system includes a media sensor to detect a presence of media at a particular point within the printing system. A stepper motor moves media through the printing system. A controller 1) monitors, for at least one pass of the media, a number of steps of the stepper motor to pass the media between the media sensor and a print position, 2) stores the number of steps of the stepper motor in a memory device, and 3) adjusts operation of subsequent passes of the media based on stored number of steps. A memory device of the printing system stores the number of steps of the stepper motor, for at least one pass of the media.

  • Patent number: 11141996
    Abstract: Either during message selection in an industrial printer (e.g. ink jet or laser marking) for printing onto objects carried past it on a conveyor, or during printing, or both, a printer displays an image associated with the message proposed for printing or being printed. The image may be a picture (e.g. a photograph) of the object on which the message should be printed or the intended customer/end user or the intended use of the object on which the message should be printed. Since a human operator can usually identify an object or intended customer/use more quickly and accurately from a picture than from text, this reduces errors in message selection and/or helps the detection of an incorrect message during printing. The image may be displayed with the associated message or without it.
