A printing system includes: a control unit; and a printing device including: a supply unit configured to be attached with a supply roll configured by an ink ribbon; a winding unit configured to be attached with a winding roll for winding the ink ribbon fed out from the supply roll; a ribbon motor configured to rotationally drive at least one of the supply unit and the winding unit; a thermal head configured to perform printing by heating the ink ribbon transported from the supply roll toward the winding roll by driving the ribbon motor; and a head drive source configured to move the thermal head. The control unit is configured to control the ribbon motor to decrease tension of the ink ribbon when the thermal head is moved in a first direction, in which the tension of the ink ribbon increases, with the head drive source.

A printing device for printing tickets in public places, with an anti-paper jam system in which an optical sensor for detecting the presence of paper is arranged at a zone where a rise of the paper occurs in case of occlusion of the paper outlet mouth; before the start of a print, the paper is retracted with respect to the sensor, whereby the sensor is OFF; when the print starts, the paper advances until arriving in front of the sensor, whereby the sensor turns ON; from this moment on, if the to sensor returns OFF, it means that the paper is no longer detected by the sensor, because it has been raised by an occlusion, whereby the advancing of the paper is interrupted.

The disclosure discloses a printer including a memory storing computer-executable instructions. In an index value detecting process, pulse count index values are detected. In a remaining amount determining process, first process, second process, third process, and fourth process are executed. In the first process, an Nth determination object value is calculated from an Nth and an N+1th pulse count index values. In the second process, an average value is calculated from a plurality of successive pulse count index values in a range including a latest value that is an Nth pulse count index value when N is an even number or is an (N−1)th pulse count index value when N is an odd number of three or more. In the third process, a remaining amount rank corresponding to the Nth determination object value is determined. In the fourth process, a rank display corresponding to the remaining amount rank is performed.
