摘要:
A printer includes a printer body, a lid, a lock, a lock lever, and an open lever. The lid is attached to the printer body to be opened and closed. The lock locks a platen roller attached to one of the printer body and the lid. The lock lever unlocks the locked platen roller. The open lever is so provided on the lid as to slide. The open lever slides to press the lock lever to open the lid.

A printer includes a printer body and a lid. The printer body includes a recording paper holder configured to accommodate a roll of recording paper and a projection provided on a bottom surface of the recording paper holder that contacts the recording paper. The lid is attached to the printer body to be opened and closed relative to the printer body.

A method of controlling a printer includes measuring a first voltage value of a power supply of the printer before energizing heat generating elements of a print head of the printer. The method also includes calculating, by a controller of the printer, the number of heat generating elements that are simultaneously energizable based on the measured first voltage value of the power supply, an end voltage value of the power supply, an internal resistance value of the power supply, a resistance value of each of the heat generating elements, and a current value of an electric current flowing through a motor of the printer for conveying recording paper. The method further includes performing printing on the recording paper by the print head using the heat generating elements of the calculated number.
