PROBLEM TO BE SOLVED: To lighten a burden of CPU of a printer and thereby' to enable improvement of reliability and reduction of cost by executing maintenance operations such as a purge operation and a flush operation for an ink jet type printing head on the basis of a maintenance instruction outputted from a host computer. SOLUTION: Each block inside CPU 30 is constructed of an LF motor control part 31 controlling an LF motor 16, a CR motor control part 32 controlling a CR motor 12, a head control part 33 controlling discharge, of ink of a printing head 10, a purge control part 34 controlling a purge device 18, a cap control part 35 controlling a cap device 15 and a cap timing detecting part 36 detecting the timing of capping. On the other hand, a printer driver 21 for making a printer 1 execute printing is provided in a host computer 20. In the printer driver 21, a flush timing detecting part 22 which controls the time for making the head control part 33 execute a flush operation and instructs a printing data output part 25 to output a command to make the printer 1 conduct the flush operation on the basis of the time is provided. |
