  • Patent number: 11117407
    Abstract: 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.

  • Patent number: 11040538
    Abstract: An inkjet printer includes a maintenance solution supply mechanism. In response to switching of a three-way valve provided in an ink pipe, a maintenance solution is supplied from a maintenance tank to each head through a maintenance pipe. The maintenance tank is a common tank. This suppresses size increase of the printer compared to provision of an individual maintenance tank for each head. The maintenance pipe is connected to the ink pipe at a position downstream of an intermediary tank. This eliminates the need of replacement of ink in the intermediary tank by the maintenance solution during supply of the maintenance solution. This allows reduction in the consumptions of the ink and the maintenance solution.
