  • Publication number: 20240086664
    Abstract: Embodiments of the disclosure provide for improved print position compensation, for example to improve accuracy of print job(s) performed by a printer. The print position compensation enables an offset of the time until printing occurs on a print media to account for changes and/or erroneous movement in a print media, such as due to slippage and/or other results of a force applied to the print media. Particular embodiments determine data values derived both for an output phase and a retraction phase of the printer's operation. Various embodiments generate a print position compensation based on sensor-based edge position distances determined during each of a media output phase and a media retraction phase. Alternatively or additionally various embodiments generate a print position compensation based on sensor-based media movement phase timestamp differentials determined during each of a media output phase and a media retraction phase.

  • Patent number: 11155102
    Abstract: Methods for converting an image to source script are provided. Generally applied to thermal printers, the methods may assist users in reproducing or amending a label without actual source script. In one embodiment, a mobile device comprising a software application may be able to scan an image, for example a barcode label. The software application may use an image processing library to recognize smart object fields in the captured image, including text, barcodes, image and shapes and then may translate the smart object information to a printing language script automatically. The application may provide the capability to a user to adjust the parameters specific to each of the identified smart objects. Once the user makes the necessary changes, a script file may be generated based on the updated smart object information. Then, the label may be sent to a printer from the application itself.
