An information processing device includes a controller. The controller acquires an appearance image configured of a plurality of colors, identifies the plurality of colors configuring the acquired appearance image, and specifying a plurality of printing medium types based on the plurality of identified colors. The plurality of printing medium types includes a first printing medium type and a second printing medium type. The controller generates a first print dataset and a second print dataset by using the appearance image. The first print dataset corresponds to the specified first printing medium type. The second print dataset corresponds to the specified second printing medium type.

In sensor determination processing, each of a transmission-type optical sensor and a reflection-type optical sensor detects a label position, and first transport for transporting the printing medium is executed so that a first label position, which is detected by a first sensor succeeding in detecting the label position first, arrives at a printing position. When the first transport is terminated before a second sensor being another sensor succeeds in detecting a label position during the first transport, a first sensor is determined as a sensor to be used for detecting a label position. When the second sensor succeeds in detecting a label position during the first transport, a sensor succeeding in detecting the first label position or a second label position detected by the second sensor, which is closer to the printing position, is determined as the sensor to be used for detecting a label position.

An adhesive label is provided. The adhesive label includes an adhesive patch that covers at least 50% but less than 85% of a backside surface of the adhesive label and that is at least partially horizontally and vertically centered on the backside surface.

A printing apparatus includes: a housing having a discharge port through which a printing medium being allowed to be discharged; an installation part to which a unit being removably installable to the installation part, the unit being configured to surround at least a part of the discharge port in a case the unit is installed, the unit being configured to perform specific processing on the printing medium; and a lid member removably installed to the installation part, the lid member being installable to the installation part in a case the unit is not installed to the installation part.

A device for providing a marking arranged or arrangeable around an object includes: a mechanical interface for releasably or irreversibly mounting the device to a printer; a material interface for receiving a print medium, which is printed by the printer using a print head, as a printed product in a longitudinal direction; at least one eccentric supported at the material interface to be pivotable about a pivot axis; and at least one print head actuator for moving the at least one eccentric to a first pivot position and to a second pivot position different from the first pivot position to provide the marking originating from the printed product. The eccentric, in a state of the device mounted to the printer using the mechanical interface, moves the print head and the print medium towards each other into a printing position for printing the print medium when the eccentric moves.

A printer configured to contain a media cartridge, wherein the media cartridge includes: a base defining a media chamber and including a lower wall and an opposing upper wall; an identification circuit disposed on the lower wall, the identification circuit configured to engage with an electronic interface of a printer; a ledge on the upper wall of the base, the ledge configured to receive downward pressure from an inner surface of a lid of the printer in a closed position; wherein the identification circuit is aligned with the ledge to receive at least a portion of the downward pressure.

An image formation apparatus according to an embodiment may include: a discharge unit configured to transport printed media from a discharge port to an outside; and a controller configured to cause the discharge unit (i) to perform a holding operation to hold a part of a first group of printed media corresponding to a first print pause sheet number set in a setting unit at the discharge port by the discharge unit, and (ii) when the part of the first group of printed media is removed from the discharge port, to transport a second group of printed media corresponding to a second print pause sheet number set in the setting unit from the discharge port toward the outside and to perform the holding operation to hold a part of the second group of the printed media with being exposed to the outside from the discharge port.

A movable paper guide structure of a label printer includes: a paper guide body installed in the label printer including a roller and a print head; a movable unit that is movably installed on the paper guide body close to one end of the print head, adapts to a displacement of the roller and the print head because of a changed contact position, and keeps approaching the print head during a print process of the label printer for neither gap between the tip of the movable unit and the print head nor other problems such as a label sticker on printing paper improperly peeled off, printing crooked and paper jam.

The printing device comprises: a print head for printing on a tape; a platen roller for conveying the tape by rotation with the tape held between the print head and the platen roller; a supporter for rotatably supporting the platen roller; and a cam including a first guide for releasing pressing of the platen roller against the print head and a second guide for pressing the platen roller against the print head.

A label printer includes a printer, a storage unit, a display, and a processor configured to generate print information for issuing a label for an item by the printer, store in the storage unit a first count of labels that have been issued with the print information in association with first label identifying information, generate a first screen to be displayed on the display and through which a user operation to change the print information can be input, and after the print information is changed through the first screen, issue a label for the item with the changed print information, store in the storage unit a second count of labels that have been issued with the changed print information in association with second label identifying information, and reduce the first count of labels stored in the storage unit by the second count of labels.
