Provided is a printer system for printing a repositionable note. The system includes a printer that prints a repositionable note and a cartridge that accommodates the repositionable note and is coupled to the printer. The cartridge includes an indication unit that indicates color information previously defined for the repositionable note accommodated in the cartridge, and the printer includes a sensing unit matched with the indication unit included in the cartridge to sense color information of the repositionable note indicated by the indication unit and recognizes a color of the repositionable note accommodated in the printer and changes a Bluetooth search name according to the color of the repositionable note. The system further includes a user client that can be linked to the printer via Bluetooth and is connected to a predetermined printer by using the Bluetooth search name.

An image forming apparatus includes a main assembly including an image forming portion configured to form an image on a sheet; a front cover mounted on a front side of the main assembly and configured to expose the image forming portion by being rotated from above toward below about a rotational axis crossing a vertical direction; a fixing portion configured to fix a position of the front cover in an open state; an exchange unit detachably mountable to the image forming portion in the open state of the front cover; and a projecting portion provided above the front cover in the vertical direction and configured to project information on exchange of the exchange unit onto an inner surface of the front cover in the open state when the exchange unit is to be exchanged.

The disclosure discloses a non-transitory computer-readable medium storing a storage body management program for executing steps. In a registration step, a total number of owned storage bodies including the storage body attached to an attaching part is acquired and registered. In a totalization step, consumption amounts of the storage bodies in the printer are totalized on the basis of an identification result and a detection result. In a calculation step, an average consumption amount per unit period of the storage bodies are calculated on the basis of a totalization result. In a prediction step, a consumption completion timing of the storage bodies is predicted on the basis of a registration result and a calculation result. In an order step, an order process for at least one type of the storage bodies is executed in accordance with a prediction result and an expected delivery period of the storage bodies.

A system for detecting the level of a media supply in a printer has a frame having a support for seating the printer thereon. A first light source is positioned on the support and is energizable to direct a first beam of light into the printer. A first detector is positioned on the support and provides an analog signal in response to reflection of the first beam of light from within the printer. A control logic processor is in signal communication with the first detector and compares the analog signal to a stored/predetermined value and reports a low media condition according to the comparison.

To use roll paper up to a terminal end of a last printing sheet and prevent the printing sheet from dropping after printing on the last printing sheet in a printer, the last printing sheet is stopped such that a side downstream of the terminal end of the last printing sheet in a feeding direction is located at a nipping position where the printing sheet is nipped by a thermal head and a platen roller if the terminal end of the last printing sheet in the roll paper is detected.

The present disclosure relates to a printer and a method of loading one or more papers into printer tray. In an aspect, the proposed printer can include a printer tray configured to hold a plurality of papers to be used for printing; and a paper sensor configured to sense when number of papers in the printer tray is below a defined threshold, such that when the number of papers in the printer tray is below the defined threshold, the paper sensor issues a notification message to a drone that in turn is configured to, based on the received notification message, pick up and carry one or more papers from a paper storage shelf and load the picked up one or more papers into the printer tray.

The disclosure discloses a printer including a CPU that executes a detection process, a first determination process, and a first mode switching process. In the detection process, a type of a storage body is detected. In the first determination process, it is determined on the basis of a detection result whether the type of the storage body attached to the attaching part is a first type in an ordering state associated with insufficiency in quantity or a second type other than the first type. In the first mode switching process a control mode is switched from a normal mode prepared in advance correspondingly to the second type to a medium-saving mode prepared in advance correspondingly to the first type for reducing a consumption amount of the print-receiving medium than the normal mode, in the case that the type is determined as the first type.

Systems and method for estimating a remaining amount of a consumable resource are provided. According to one method, a first step of detecting the center of mass of a mobile printer is conducted, wherein the mobile printer comprises print media. The method may also include a step of determining a remaining print media level based on the detected center of mass.

A paper roll, in which a paper strip is wound in the form of a roll, includes a marker formed of a medium containing a phosphorescent material on an end portion of the paper strip that extends from a finishing end of the paper roll to a position that is a predetermined length from the finishing end. A printer includes a roller configured to convey paper supplied from the paper roll, a printing head configured to print information on the paper conveyed by the roller, one or more ultraviolet light emitting diodes (LEDs) positioned downstream of the printing head in a conveyance direction of the paper, and a control unit configured to turn on the LEDs to irradiate the paper on which the information has been printed and discharged out of the printer.
