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.

Abstract: A thermal head control device includes: a printing rate calculation range determination unit configured to determine, as a printing rate calculation range, a range from a left-end energization dot to a right-end energization dot among energization dots present in printing data corresponding to heating elements to be controlled among a plurality of heating elements included in a thermal head; a printing rate calculation unit configured to calculate a printing rate of the printing rate calculation range determined by the printing rate calculation range determination unit; an energizing time calculation unit configured to calculate an energizing time for which a current is caused to flow through the heating elements based on the printing rate calculated by the printing rate calculation unit; and an output unit configured to output a control signal for driving the heating elements to be controlled of the thermal head, based on the calculated energizing time.
