A printer includes: a transfer unit configured to transfer printing paper in a printing direction; a printing unit configured to print information on transferred printing paper; a detection unit installed to face discharged printing paper on a printing paper discharge portion side, and configured to acquire measured values by detecting light while printing paper is transferred or when the transfer of printing paper is stopped; and a control unit configured to collect measured values of the detection unit while printing paper is transferred, to calculate a reference value by using the collected measured values, and to determine whether printing paper has been removed by comparing the calculated reference value with a measured value acquired by the detection unit when the transfer of printing paper is stopped.

A portable hybrid hand labeler is disclosed that relies on mechanical motion, which eliminates the need for motors and the corresponding energy required to run the motors. The portable hybrid hand labeler also houses an ink jet head and a digital print mechanism, which offers the user infinite print flexibility via downloadable print bands. The portable hybrid hand labeler is preferably battery driven, and comprises a unique drive system and mechanism to harvest the kinetic energy from the trigger pull and a display panel with a solar panel to collect solar energy to trickle charge the battery pack, thereby increasing usage time between charges.

A printing device includes: a motor; a rotary body driven by the motor to rotate; a movable blade driven by rotation of the rotary body to cut a printing tape; a gear mechanism provided on a power transmission path from the motor to the movable blade; a first detector outputting a first signal based on a rotated position of the rotary body; a second detector outputting a second signal based on the rotated position, and a controller performing positioning the rotary body to a predetermined reference rotated position. The positioning includes: starting rotating the rotary body in one direction on the basis of the first signal at the time of starting the positioning; halting the rotation in the one direction of the rotary body on the basis of the second signal; and rotating the rotary body in the opposite direction for a prescribed time period after the halting is completed.

In a printing device, a supply portion is configured to convey a tape in its longitudinal direction. The tape includes: a plurality of labels arranged continuously in the longitudinal direction; and a plurality of storage elements provided on respective ones of the plurality of labels. A first storage element is provided on a first label and configured to store first authentication data. The second storage element is provided on a second label and configured to store second authentication data. A printing portion is configured to print on the plurality of labels. A controller is configured to perform: reading the first authentication data from the first storage element and the second authentication data from the second storage element by a reading portion; and determining whether the first authentication data is correlated to the second authentication data to meet an authentication condition.

A device for providing a marking arranged or arrangeable in a circumferentially closed manner around a prolate object includes: a material interface for receiving a printed product output from a printer; a print signal interface for acquiring a control signal related to the printed product output; at least one sensor for acquiring a control signal related to providing of the marking; and at least one actuator for arranging the marking on the object in a circumferentially closed manner or to provide the marking for circumferentially closed arrangement depending on the control signal related to the printed product output and the control signal related to the providing of the marking using the printed product output by the printer.

According to one embodiment, there is provided a printer including a print head, a platen roller, a sheet position sensor, an antenna, and a movable portion. The print head is configured to print on a strip-shaped sheet. The platen roller is configured to move the sheet pinched between the platen roller and the print head along a longitudinal direction of the sheet. The sheet position sensor is provided on a substrate disposed on an upstream side of the print head in a conveyance direction of the sheet, and is configured to detect a position of the sheet. The antenna is provided on the substrate and is configured to write information to a wireless tag provided on the sheet. The movable portion is configured to move the substrate along a width direction of the sheet.

A sheet detection device includes a sheet guide disposed between a sheet feeding opening into which a sheet is inserted and a printing mechanism of printing on the sheet, the sheet guide including a guide surface through which the sheet passes, a sheet detector including an optical sensor that detects a predetermined position of the sheet, an opening formed in the guide surface, the sheet detector being disposed inside the opening and the optical sensor being exposed through the opening, and a transparent guide cover provided in the guide surface to cover at least a first border position between the sheet detector and the opening on an upstream side in a sheet transport direction.

A tape cassette includes a box-like housing, a tape mounted within the housing, a hole and a first indicator portion. The housing includes a top wall having a top surface, a bottom wall having a bottom surface and opposing the top wall, and a front wall having a specified height and being formed along peripheries of the top wall and the bottom wall. The hole is provided in the front wall. The first indicator portion includes at least one first aperture and indicates a first element among a plurality of elements of a type of the tape. The first indicator portion is provided in a portion, spaced from the front wall, of the bottom wall. The hole and the one first aperture is located to intersect a virtual line orthogonal to the front wall when viewing along a vertical direction orthogonal to the top wall and the bottom wall.

A printing apparatus, having a casing, a printer, and a battery cover, is provided. The casing includes a battery compartment, to which a battery is attachable, and a terminal arranged inside the battery compartment. The printer is powered by the battery to print an image on a printable tape. The battery cover is attachable to the casing and, when at an attached position, covers at least a part of the battery compartment. The casing includes a guide arranged outside the battery compartment to guide the battery cover toward the attached position in the casing. The battery cover includes a first wall portion, which contacts the guide at an outer face thereof and slides along the guide as the battery cover moves toward the attached position, and a pressing portion to press the battery in the battery compartment against the terminal as the first wall portion slides along the guide.

In accordance with an embodiment, a label printer comprises a transmission type sensor configured to enable a first light emitting element to emit light to irradiate a printing medium with the light and to detect light transmitted through the printing medium; a reflection type sensor configured to enable a second light emitting element to emit light to irradiate a printing medium with the light and to detect light reflected by the printing medium; and a light emission control module configured to alternately switch a single light emission period in which either the first light emitting element or the second light emitting element emits light and a both light emission period in which both the first light emitting element and the second light emitting element emit light.
