A printer in one example includes a thermal printhead with resistive heating elements. A motor is provided in the printer for conveying paper to the thermal printhead. A power supply is provided to supply power to the thermal printhead and the motor. A processor is configured to cause the supply of power to the motor to be paused after the supply of power to the thermal printhead exceeds a power threshold value and then to resume the supply of power to the motor after a predetermined period of time elapses after the pause of the supply of power to the motor.

A visual security feature is provided that is disposed on a target. The visual security feature includes two substantially transparent layers. At least one of the two substantially transparent layers is present in an image-wise pattern.

A base material processing apparatus includes a tension detector that detects tension on a base material that is being transported, an encoder that detects the amounts of rotational drive of rollers that transport the base material, edge position detectors that detect the position of an edge of the base material in the width direction, and a transport displacement calculation part that calculates a transport displacement of the base material in the transport direction. The transport displacement calculation part includes an operation unit that has completed learning through machine learning and outputs the transport displacement on the basis of at least one of the result of detecting the tension, the result of detecting the amounts of rotational drive of the rollers, and the result of detecting the position of the edge. Accordingly, the transport displacement can be detected with high accuracy and low cost.

A printer includes a first accommodating portion, a supply roller, a recording device, a cutter configured to cut a recording medium into a first recording medium and a second recording medium, a second accommodating portion, a third accommodating portion that accommodates an unrecorded second recording medium that is the second recording medium on which an image has not been recorded by the recording device, and a switcher. The third accommodating portion is movable between a first position at which the third accommodating portion receives the unrecorded second recording medium cut by the cutter and a second position at which the unrecorded second recording medium accommodated in the third accommodating portion is in contact with the supply roller. The supply roller is configured to supply the unrecorded second recording medium accommodated in the third accommodating portion that is positioned at the second position.

Certain examples described herein relate to a buffer unit for a printing system. In certain cases, a measurement device is used to obtain measurement data representing an optical property of a printed image on a substrate. A buffer unit receives the substrate downstream of the measurement device and places the substrate in a queue. In certain cases, a controller determines, based on the measurement data, whether the printed image comprises a defect. Responsive to determining that the printed image does not comprise a defect, the controller causes the substrate to be moved from the buffer unit to an output stack. Responsive to determining that the printed image comprises a defect, the controller causes the substrate to not be moved to the output stack.
