Abstract:
1. A printing device comprising: a printing section that has a print head configured to deposit printing matter onto a printing medium; a conveying section configured to cause the printing medium to travel in a prescribed conveyance direction in a relative manner, using the print head as a reference; a data conversion section configured to acquire a print data from a host device that is configured to communicate with the printing device, and create operating data by carrying out an expansion process on the print data in accordance with a compression format of the print data, and by carrying out a description process of the print data in accordance with a description format of the print data; a speed-acquiring section configured to acquire a creation speed for carrying out the expansion process and the description process; and a data-length-instructing section configured to receive the creation speed from the speed-acquiring section and a communication speed between the printing device and the host device, set a data length of a next print data based on the creation speed and the communication speed, and send the data length to the host device, the next print data being a print data to be received next to the print data from the host device, the data-length-instructing section shortening the data length of the next print data and sending a shortened data lengh of the next print data to the host device in response to the creation speed being lower than a prescribed speed; and a printing control section configured to control the printing section to cause the printing matter to be deposited onto the printing medium on the basis of the operating data and control the conveying section to cause the printing medium to travel, the printing control section reducing the speed at which the printing section deposits printing matter onto the printing medium to a speed lower than in the case where the creation speed is higher than the prescribed speed in accordance with a next operating data created based on the next print data including the shortened data length in response to the creation speed being lower than the prescribed speed.
