PROBLEM TO BE SOLVED: To solve the problem that a main power source loaded in a printer of an inkjet system becomes large consequent on the fact that a printing resolution is made highly fine and a printing speed is made high. SOLUTION: The printer of the inkjet system is loaded with (a) an image processing part which processes and supplies image data to a printing head, (b) the main power source which is connected to a commercial power supply and supplies a first power to the printing head, (c) a sub-power source of a charging type which supplies a second power that compensates for the first power to the printing head when a power necessary for driving of the printing head exceeds the first power during execution of printing, and (d) a switch part which is located on a feeding line of the power and electrically connects the sub power source to the feeding line of the power when the power necessary for driving of the printing head exceeds the first power.
