Abstract: A printing apparatus that has a plurality of functions including a printing function and is capable of executing printing with resolution of 300 dpi or more includes a plurality of operating units including a printing unit and a power supply unit. The power supply unit includes a substrate, an input terminal that receives an alternating voltage, a smoothing capacitor that smooths the alternating voltage, a thermistor that detects a temperature, and a comparator that compares a signal output from the thermistor with a standard signal and outputs a notification signal. The input terminal, the smoothing capacitor, the thermistor, and the comparator are mounted on the substrate. The supply of power from the power supply unit is stopped based on the state of the notification signal. A gap between the input terminal and the thermistor is longer than a gap between the input terminal and the smoothing capacitor.
Abstract: A decurling device includes a first conveyance path, a second conveyance path, a first switch, a decurler, and a controller.

Abstract: A liquid container is enabled to contain a liquid therein. An outer wall of the liquid container has a first surface, a second and a third surfaces are adjacent to the first surface, and the second surface and the third surface face each other. The first surface has a space in which a storage element storing the information on the liquid container is contained. The first surface and the second surface have a first recessed portion that crosses a boundary between the first surface and the second surface, and the first surface and the third surface have a second recessed portion that crosses a boundary between the first surface and the third surface. The first recessed portion and the second recessed portion face each other across the space.
Abstract: Printers and other machines providing tangible outputs are provided. In one implementation, a printer comprises a housing having a fixed structure and a movable cover configured to be movable with respect to the fixed structure. The printer also includes a printing mechanism that is disposed inside the housing and is configured to print an image on a medium. The movable cover is movably attached to the fixed structure via a first pivoting mechanism that defines a first pivoting axis. The movable cover is configured to be pivoted about the first pivoting axis of the first pivoting mechanism. Also, the movable cover comprises a plurality of linked slats, each pair of adjacent linked slats being linked together by a second pivoting mechanism. Each second pivoting mechanism includes characteristics enabling a user to detach the adjacent linked slats from each other.
Abstract: A method of operating a transfer printer (1), the transfer printer comprising first and second spool supports each being configured to support a spool (3,4) of ribbon (2), a ribbon drive configured to cause movement of ribbon (2) from the first spool support to the second spool support along a predetermined ribbon path, and a printhead (7), the printhead being configured to selectively transfer ink from the ribbon to a substrate as the substrate is moved relative to the printhead in a direction of substrate movement. The method comprises driving the ribbon in a direction parallel to the direction of substrate movement, printing a first plurality of images onto a first respective plurality of substrates, driving the ribbon in a direction opposite to the direction of substrate movement, driving the ribbon in the direction parallel to the direction of substrate movement, and printing a second plurality of images onto a second respective plurality of substrates.
Abstract: In one example, a structure to hold a printhead includes a surface defining an opening through which the printhead orifices may be exposed for printing and a replaceable shield shielding an area of the surface around the opening.

Abstract: An inkjet printer includes an m number of data setters ranging from a first data setter to an m-th data setter, and an m number of print controllers ranging from a first print controller to an m-th print controller, where m is a natural number greater than or equal to 2. Upon receiving data for ink dots, an n-th data setter sets an n-th dot group including some or all of the ink dots, where n is a natural number in a range of from 2 to m. An n-th print controller causes the n-th dot group to be formed over an (n?1) dot group. The first to the m-th data setters set the first to the m-th dot groups so that at least some of ink dots belonging to the first to the m-th dot groups overlap each other.
