Abstract: A printer includes: a nonvolatile storage section configured to be capable of keeping stored content even if a power supply is turned off; a sheet storing section configured to store a label sheet wound in a roll shape; a thermal head configured to heat a label stuck to a base sheet of the label sheet and perform printing in a process in which the label sheet, which is stored in the sheet storing section, is drawn out and conveyed in a sub-scanning direction by using a motor as a driving source; a label-position detecting section provided in a sheet conveying path, which connects between the position of the sheet storing section and the position where the thermal head is arranged, and configured to detect a label position of the label sheet; an information storing section configured to store a position of the label sheet detected by the label-position detecting section when the power supply is turned off in the nonvolatile storage section as stop position information; and a position setting section configured

Abstract: According to certain embodiments, a power control apparatus may include a setting unit, a voltage detection unit, and a control unit. The setting unit may be configured to set a charge start voltage and a charge stop voltage for a storage battery. The voltage detection unit may be configured to detect an output voltage of the storage battery. The control unit, upon being powered from an external power source, may be configured to control the charge operation of the storage battery based on a current charge state of the storage battery. The current charge state of the storage battery may be determined by comparing the detected output voltage of the storage battery with the charge start voltage and the charge stop voltage.

Abstract: If it is determined that a portable storage medium is held in a medium access unit (Yes in ACT S2) and it is determined that information to change at least one of a various setting data file storing various kinds of setting information that are necessary for printing and a program to control printing is stored in the portable storage medium (Yes in ACT S3), the information to change at least one of the setting data file and the program is loaded to a setting data storage unit (ACT S4). Thus, if the program and the setting data file are set and copied to a predetermined area in the portable storage medium, the program and the various setting data file can be automatically set by inserting and starting up the portable storage medium in the medium access unit of another printer. Therefore, many printers can be easily upgraded.
