An electronic apparatus includes a power switch element configured to switch on and off power supply, a power-source supply controller configured to request an external apparatus for the power supply when coupling with the external apparatus is established, and a power switch configured to switch on and off the power switch element. The power-source supply controller includes an output unit configured to switch from a first state to a second state when the coupling with the external apparatus is established. The electronic apparatus includes a power controlling switch element between the power switch element and the output unit, the power controlling switch element being configured to keep the power switch element off by remaining off until the power switch is operated when the output unit is in the second state and the power switch element is off.

A recording apparatus includes a first power storage unit, a second power storage unit, a connection unit configured to connect with an external power source via an insertable/removable connection unit, and a recording unit configured to perform recording on a recording medium by using the power of either one of the first and the second power storage units, wherein the recording apparatus further includes a charging unit configured to charge the first or the second power storage unit, a charging target switching unit configured to change a charging target to be charged by the charging unit, and a control unit configured to, in a state where the external power source is unconnected to the connection unit, charge the first power storage unit by using the power of the second power storage unit.

A liquid discharge apparatus includes a holder, a pre-treatment head, a smoother, and a print head. The holder reciprocally moves while holding a recording medium. The pre-treatment head discharges a pre-treatment liquid onto a surface of the recording medium held by the holder. The smoother smooths the pre-treatment liquid, which is discharged onto the surface of the recording medium, along the surface of the recording medium by a movement of the holder. The print head discharges a printing liquid onto the surface of the recording medium with the pre-treatment liquid smoothed.

A printing execution unit (111) of a printing device (100) executes printing of the printing surface identified by printing surface identification information based on printing instruction data including resultant product identification information for identifying a resultant product of printing, a total printing surface number, which is a total number of the printing surface to be printed to obtain the resultant product, printing surface identification information for identifying a printing surface, and printing data of the printing surface identified by the printing surface identification information. A printing history output unit (112) outputs a printing history indicating a result of printing executed based on the printing instruction data including the same resultant product identification information in association with the resultant product identification information.

The present disclosure is directed to a system for preventing incorrect installation of ribbon material in a printer. The system includes a spindle rotatable in a first direction or a second direction. The spindle is capable of supporting a supply of ribbon material for rotation with the spindle. The system also includes a trigger associated with the spindle. The trigger rotates with the spindle in the first direction or the second direction. The system further includes an actuator adjacent the spindle and configured to detect whether the spindle is rotating in the first direction or the second direction via the trigger.
