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.
