PROBLEM TO BE SOLVED: To provide a printing device, a control method of the printing device and a control program of the printing device which minimizes the range of diffusion of thickened ink produced on an ejection part upon the execution of bilayer printing. ! SOLUTION: A printing device includes: a driving signal generation part 50 which drives an ejection part by supplying to an ejection part at least one of a driving signal for ejection for driving the ejection part so as to eject ink from the ejection part and a driving signal for microvibration which drives the ejection part such that ink is not ejected from the ejection part; ejection parts D1, D2 which form a background layer on a recording medium by ejecting ink of a background color when the driving signal for ejection is supplied; and ejection parts D3, D4 which form an image layer on the recording medium by ejecting ink of an image color when a driving signal for ejection is supplied. The driving signal producing part 50, when forming the ba |
