Publication number: 20240086664Abstract: 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.Type: ApplicationFiled: November 16, 2023Publication date: March 14, 2024Inventors: Cheng Khoon NG, Heng Yew LIM, Shufeng ZHENG, Jang Wei CHAO
