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: 10730297Abstract: Provided herein is a printing apparatus that includes a printhead assembly and a plurality of printhead pressure load modules that are adjustable on a shaft of a printhead pressure load assembly and engaged with a printhead member. The printhead pressure load module has a hollow housing, a plunger member, and a rotary cam. The plunger member and the rotary cam are movably engaged in the hollow housing. The rotary cam includes a plurality of channel members defined at an outer surface. Each channel member has a depth that is different from a depth of an adjacent channel member. A movement of the plunger member inwardly through the hollow housing defines a position of the rotary cam along the longitudinal axis with respect to the hollow housing. Position change of the rotary cam defines a force that acts on a pressure contact member and adjusts a load on the printhead assembly.Type: GrantFiled: June 21, 2018Date of Patent: August 4, 2020Assignee: Datamax-O'Neil CorporationInventors: Yaw Horng Yap, Chin Young Wong, Ching Hong Chua, Eng Hing Lim

Patent number: 10399369Abstract: The present invention embraces a method and apparatus for providing feedback to a user on the status of media or ribbon of a printer. The feedback may be provided by incorporating a feedback mechanism in a hanger of a printer. The printer may be a thermal printer, but may be another type of printer. The feedback mechanism of the printer may be designed to work with one or more sensors to provide a feedback loop so that without an input from a user, the printer is able to detect the presence/absence of media or ribbon, as well as determine the width of the loaded media or ribbon. In another embodiment, the feedback mechanism is able to determine the weight of the roll of media or ribbon and hence determine the quantity of media or ribbon available on the hanger.Type: GrantFiled: October 23, 2017Date of Patent: September 3, 2019Assignee: Datamax-O'Neil CorporationInventors: Chin Young Wong, Yaw Horng Yap, Sébastien Michel Marie Joseph d'Armancourt, Boon Kheng Lim

Patent number: 10189285Abstract: A self-strip media module in a printer is provided. The self-strip media module includes a peel bar having a length at least as great as the length of a platen roller and being rotatably engaged at the ends of the platen roller. The media includes a series of labels adhered to a liner. The media is fed over the peel bar and between the platen roller and a mid-chassis. The peel bar may be rotated towards the discharge side of the platen roller, pulling the media over the platen roller and over itself. A thermal print head is lowered onto the media over the platen roller and to print on the labels. The printer advances the media over the peel bar. The labels are stripped from the liner when the media advances around the peel bar.Type: GrantFiled: March 29, 2018Date of Patent: January 29, 2019Assignee: DATAMAX-O'NEIL CORPORATIONInventors: Chin Young Wong, Sébastien Michel Marie Joseph d'Armancourt, Ching Hong Chua, Yaw Horng Yap
