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.

Printing apparatus, control method, program, information processing apparatus, and printing system

A printing system includes a host apparatus configured to transmit a command to a printer, and a printer configured to perform processing based on the command received from the host apparatus. The host apparatus is configured to convert the command based on a conversion condition when the command satisfies a predetermined condition, and transmit a conversion code obtained through the conversion to the printer as the command. The printer includes a receiver configured to receive the command from the host apparatus, a command converter configured to discriminate whether the received command is the conversion code obtained through the conversion based on the conversion condition, and when the command is the conversion code, convert the conversion code into the command based on the conversion condition, and a command processor configured to execute the command obtained through the conversion by the command converter when the command is the conversion code, and execute the received command when the command is not the conversion code.
