Ink in an ink tank is fed through a dissolved gas control filter to a printer head. A gas pressure changing mechanism reduces pressure in a gas pressure control tank. In response, the dissolved gas control filter removes gas dissolved in the ink.

A gas pressure measuring part measures the sum of these pressures as pressure in the gas pressure control tank. Then, a controller determines when time of exchange of the dissolved gas control filter has come based on the magnitude of a gradient of gas pressure variation in the gas pressure control tank.
