Abstract: The electronic hand stamp (1) includes an inkjet printhead with nozzles directed toward a bottom side (4) of the electronic hand stamp (1), a control circuit (30) and a motion detector. The control circuit (30) is connected to the motion detector and to the inkjet printhead and configured to control the inkjet printhead in response to readings received from the motion detector. The electronic hand stamp (1) includes at least four indicator LEDs (10-17) connected to the control circuit (30). At least one of the at least four indicator LEDs (10-17) is arranged on every side perpendicular to the bottom side (4) of the electronic hand stamp (1).

Abstract: A method and token (3) for corroborating a document (25) includes having a registered token (3) with a token identity. The token (3) is able to print visual markings. A document identifier is obtained (18) based on at least the token identity and a timestamp. The document identifier is encoded (19) into a visual marking (24), and the visual marking (24) is applied to the document (25). A copy of the document (25) is obtained (27) with or without the visual marking (24), and copy is stored in association with the document identifier. The token (3) includes storage holding a token identity and a printing unit. The token (3) is configured to receive the visual marking (24) encoding a document identifier associated with the token identity and to print the received visual marking (24). A method also verifies a document (41) having a corresponding visual marking (42).

Abstract: A method of controlling a hand-operated printer (3) includes detecting a transverse movement of the hand-operated printer (3) after finishing a first swath (1). The method compares a transverse distance covered by the transverse movement with a predetermined transverse distance (11) between said first swath (1) and a second swath (2). A transverse-stop signal is emitted when the transverse distance covered by the transverse movement reaches the predetermined transverse distance (11).

Abstract: A docking station (1) is for an electronic hand stamp having an inkjet printhead. The docking station (1) includes a body (2) having a rest surface (4) for receiving a substantially flat bottom side of an electronic hand stamp and a border (5) at least partially framing the rest surface (4). The docking station (1) also includes at least one wiper element (3) connected to the body (2) and that projects on one side from the body (2). The wiper element (3) includes a wiper blade (17) for manually sweeping across an inkjet printhead.

Abstract: The invention relates to a hand-held and hand-operated printing device having a print (2) head assembly comprised in a housing (1) for a hand-held and hand-operated printing controlled by a processor (4), and a method therefore. The position of the printing device on a print medium is sensed in relation to pixels to be printed. An image is stored in a memory together with its mutual image pixel coordinate data. Image pixels are printed onto the print medium through nozzles (12) in a print-head array (60) in accordance with the pixel coordinate data during a printing sequence. The image is built-up through sectional printing whereby each section has at least one print area interfacing at least one other print area, said interfacing print areas being correlated to fill-out transition print areas during printing of said sections through at least one transition printing pattern by omitting printing of some pixels in said transition print area.

Abstract: The present invention relates to a printing device (10; 40) for printing on a surface comprising: a print head (12; 41) including an ink reservoir (20), a housing (11) that is pressed against a printout surface (17). The print head (12) is movable along and guided by one or more steering beams (30) in the housing (11) and ejecting ink drops on the printout surface (17). The device further include means to determine parameters of movement of the print head (12) using at least one sensor (16) for determining the parameters of movement of the print head (12) in relation to the printout surface (17), and means (21) for controlling a stream of ink drops against said printout surface (17) according to a predetermined pattern, in accordance with the determined parameters. The invention also relates to a method for printing on a surface.

Abstract: The invention relates to a sensor and assembly comprised in a housing for a hand-held and hand-operated printing device controlled by a processor, and a method therefor. It provides that the assembly comprises an arrangement and a method for preventing skew and cutting of printed images.

Abstract: The present invention relates to a handheld printing device (1) having a print head for printing a printout on a printout surface. The handheld printing device (1) comprises an interface for mechanical and electrical connection to a handheld mobile unit (9) capable of communicating with other units for information retrieval. The entire unit, including the handheld mobile unit (9) and the connected handheld printing device (1) is manually steered over said printout surface with the aid of one or more positioning sensors disposed in the printing device 1 and co-operating with a micro controller circuit. Thereby information retrieved by the mobile unit, or stored therein, can be printed by said printing device (1). The invention also relates to a handheld mobile unit (9) connectable to said handheld printing device (1).
