Abstract: A printer includes: a first connector to be used to input electric power supplied from an outside; a second connector to which a communication terminal is to be connected, and which is to be used to output at least a part of the electric power to the connected communication terminal; a printing control unit configured to control operation of a printing unit configured to perform printing on recording paper; and an adjustment unit configured to adjust a maximum amount of the electric power to be output from the second connector, of the electric power supplied from the outside, to a first amount of power when the printing unit is not under a printing operation, and adjust the maximum amount of the electric power to be output from the second connector to a second amount of power when the printing unit is under the printing operation, the second amount of power being smaller than the first amount of power.

Abstract: A printing apparatus includes: a user-setting-value acquiring unit configured to acquire a user setting value indicating a remaining amount of paper on a paper roll, the user setting value being set by a user; a first detection unit configured to detect that a physical quantity correlated with a remaining amount of paper on the paper roll has become equal to a first threshold value; a second detection unit configured to detect that the remaining amount of paper on the paper roll has become equal to a second threshold value; a post-detection length acquiring unit configured to acquire a post-detection length being a length of paper used from the paper roll from a time when it is detected that the physical quantity has become equal to the first threshold value until the remaining amount of paper on the paper roll becomes equal to the second threshold value; and a notification unit configured to notify that, when a new paper roll is used and a length of paper used from the new paper roll from a time when it is detected that the physical quantity has become equal to the first threshold value exceeds a reference value obtained by subtracting the user setting value from the post-detection length, a remaining amount of paper on the new paper roll has become equal to the user setting value.
