Patent number: 11660895Abstract: The present invention embraces printers such as hand-held printers and mobile/portable printer. One exemplary embodiment includes “print as you glide” (PAYG) devices. Such printers may comprise a modular print engine that is removable from the printer and may allow a user to easily access and load the ribbon in the mobile print engine. The modular print engine may comprise a modular print head and an encoder that may determine the movement of the print head relative to a stationary media. When a printer is pressed against the media, the print head's burn line may be resting on the media. When the printer is stationary relative to the media, the encoder may not trigger the printing. Once PAYG is being slid or glided across the media, the encoder may start to rotate and then send a signal to a processor, causing the printer to start printing.Type: GrantFiled: July 30, 2021Date of Patent: May 30, 2023Assignee: Datamax O'Neil CorporationInventors: Chin Young Wong, Yaw Horng Yap, Ching Hong Chua

Patent number: 11461604Abstract: 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: GrantFiled: August 20, 2021Date of Patent: October 4, 2022Assignee: Datamax-O'Neil CorporationInventors: Cheng Khoon Ng, Heng Yew Lim, Shufeng Zheng, Jang Wei Chao
