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 conveyance controller configured to control a conveyor, the conveyor being configured to convey paper having a printing surface in which label portions are formed at predetermined intervals; a sensor configured to irradiate light on the paper conveyed by the conveyor to detect reflected light of the irradiated light; a detector configured to detect an output of the sensor; a moving average calculator configured to calculate moving averages of voltage values based on the output of the sensor detected by the detector; and a determiner configured to determine that a portion between an adjacent pair of the label portions has been detected based on the moving averages of the voltage values calculated by the moving average calculator, and the output of the sensor.

A printer system includes an information processing device; a printer; and a display apparatus, the information processing device being configured to control the printer and the display apparatus. A topology of the information processing device and the display apparatus includes a first topology in which the display apparatus is directly connected to the information processing device and a second topology in which the display apparatus is connected to the information processing device via the printer. The information processing device includes a processor configured to transmit to the display apparatus instruction data for the display apparatus without adding header information to the instruction data in the first topology; and transmit to the printer instruction data for the display apparatus by adding header information to the instruction data in the second topology.
