A non-transitory computer-readable storage medium stores a set of program instructions including: (a) generating; (b) generating; (c) setting; and (d) displaying. The (a) generating generates a plurality of sets of print data corresponding to respective ones of a plurality of print labels used in an overlaid state. The (b) generating generates a plurality of sets of medium type information for respective ones of the plurality of print labels. Each medium type information indicates a type of a printing medium used for creating a corresponding print label. The (c) setting sets a layering order for the plurality of print labels. The (d) displaying displays a list of the plurality of sets of medium type information on a display. The plurality of sets of medium type information is arranged in the layering order for the plurality of print labels corresponding to respective ones of the plurality of sets of medium type information.

Disclosed is a method of cutting off self-adhesive linerless endless tape labels, using a cutter of a label printer, wherein the cutter comprises a transport roller, which is rotatable about an axis of rotation, and a blade unit that is linearly travelable in parallel with the axis of rotation of the transport roller and that has a cutting blade directed in the direction toward the transport roller, where tape labels pass between the transport roller and the blade unit, and are transported further step-wise in a motorized manner, by one label, and, between two consecutive further transport steps, the blade unit is linearly traveled in a motorized manner between a start position and a target position in order to cut off a label, such that the label is completely cut off and is held at the transport roller by the blade unit in the target position of the blade unit.

A cutting device includes a support base, a cutting blade, and a holding member. The cutting blade has first and second holes and a blade edge. The blade edge has a first convex portion and a second convex portion, provided at a position corresponding to the first and second holes, respectively. In a case where the cutting blade is arranged at a cutting position, a maximum value of a distance between the blade edge and the support base within a range between the first and second holes in a longitudinal direction of the cutting blade is smaller than a maximum value of a distance between the blade edge and the support base. The cutting blade is fixed to the holding member by a first hole coupling member, and the holding member holds the cutting blade so as to be movable to the cutting position and a spaced position.

According to one aspect of the present disclosure, an applying unit that can be connected to a printer and apply an adhesive to a recording sheet includes: a roller configured to transport the recording sheet that is discharged from the printer; a sensor configured to detect the bend of the recording sheet; an applying portion configured to apply the adhesive to the recording sheet; and a control device configured to adjust the rotation speed of the roller according to the value detected by the sensor.

A printer includes a driving roller to move a medium supported on a support table in a predetermined transportation direction, and pinch roller assemblies each including a pinch roller, a support to support the pinch roller to allow the pinch roller to contact, or to be spaced from, the driving roller, and an actuator provided upstream in the transportation direction with respect to the pinch roller. The actuator includes a contact portion contactable with the support, and an operation portion to press the contact portion to the support to move the pinch roller in a direction away from the driving roller.

Disclosed is a printing device including a main body part including a body part configured to provide an internal space in which recording paper for printing certain information thereon is transferred and an opening or closing part configured to control opening or closing of the internal space, a printing part configured to print the certain information on the recording paper transferred in the internal space, and a recording paper separation part located on a downstream side of the printing part and configured to cut or cut off and separate recording paper on which particular information is printed by the printing part from the other recording paper. Here, the main body part includes includes a protruding part configured to prevent an adhesive attached to the surface opposite the adhesive surface from being accumulated by decreasing a contact area with the surface opposite the adhesive surface.

A housing is provided with a sheet ejection port for discharging sheet that passed through a printing unit upward. A cutting unit is arranged between the printing unit and the sheet ejection port and cuts the sheet by either a method of cutting the sheet in the entire width direction or a method of leaving the central portion of the sheet in the width direction. First protrusions and second protrusions protruding from the inner periphery of the sheet ejection port are provided at a plurality of locations along the width direction of the sheet. The first protrusion faces a first surface of the sheet and the second protrusion faces a second surface, which is the back surface of the first surface of the sheet. The first protrusion and the second protrusion are provided at positions deviated from each other in the sheet width direction and bend the sheet in an undulating shape in the width direction therebetween. Further, protrusion height of at least one of the first protrusions and the second protrusions in the central portion in the width direction of the sheet is lower than protrusion heights of the first protrusions and the second protrusions in other regions.

A label printer and a label printing method for precise positioning thereof are provided. The label printer includes an outer shell and a label cartridge arranged inside the outer shell, a power mechanism and a control mechanism configured to control paper output of the label cartridge and winding and unwinding of a carbon ribbon, and a print head configured to realize label printing. An inner space of the label cartridge is reasonably planed, and a linear label paper output channel and a label rollback release space are arranged, thereby ensuring smoothness of paper feeding and paper rollback, and preventing label paper from wrinkling in a rollback process. A gear transmission system is improved to realize forward and reverse rotation of gears relying on the same electric motor. A photoelectric sensor with its own reflecting prism is arranged to reduce an occupied space of the label cartridge.

A cutting device includes: a cutter blade movable between a retracted position and a cutting position; a cutter cradle facing the cutter blade; and a first lever and a second lever those operated by a user. The cutter blade performs one of a half-cutting operation and a full-cutting operation with respect to a cut target when positioned at the cutting position. The cutter cradle is movable between: a full-cutting position where the full-cutting operation is performed by the cutter blade; and a half-cutting position where the half-cutting operation is performed by the cutter blade. When the first lever is operated, the cutter blade is moved to the cutting position while the cutter cradle remains at the half-cutting position. When the second lever is operated, the cutter blade is moved to the cutting position and the cutter cradle is moved between the full-cutting position and the half-cutting position.
