Abstract: An ink jet recording apparatus performs a recording operation by ejecting ink from a recording head. The apparatus includes a first absorber configured to absorb ink, a second absorber disposed apart from the first absorber having a larger ink absorption capacity than the first absorber, and a flow path portion that does not absorb ink. The second absorber has a second lower end portion arranged below a first lower end portion of the first absorber. The flow path portion connects the first lower end portion and a portion of the second absorber below the first lower end portion. As a result, ink is prevented from overflowing from the absorbers, even if an apparatus is arranged at an angle.

Abstract: A thermal transfer print ribbon having radiation curable ink thereon is used to print on a surface of a plastic card. The use of radiation curable thermal transfer printing to print on the card surface increases the durability of the printing compared to regular (i.e. non-radiation cured) thermal transfer printing once the radiation curable ink is cured. As a result, a protective laminate or coating need not be applied to the card surface to protect the printing.

A second closing unit closes the ink supply path. A control unit is able to execute a first control mode in which the first closing unit closes the ink suction path and a second control mode in which the second closing unit closes the ink supply path.

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.
