A printing device comprising: a data acquiring unit configured to acquire image data; an image processing unit configured to generate display image data and printing image data based on the image data by with pixel value of a pixel at a first position in an image of the printing image data, performing an image process of modifying a pixel value of a first subject pixel of the printing image data at the first position or another position, the first position being determined according to a first parameter P 1 , with pixel value of a pixel at a second position in an image of the display image data, performing an image process of modifying a pixel value of a second subject pixel of the display image data at the second position or another position, the second position being determined according to a second parameter P 2 , and determining the second parameter P 2 such that a ratio (P 2 /P 1 ) of the second parameter P 2 and the first parameter P 1 is in a specified range that includes a ratio (Px 2 /Px 1 ) of a display pixel count Px 2 representing a size of the image of the display image data and a printing pixel count Px 1 representing a size of the image of the printing image data; a display unit configured to display an image based on the display image data; and a printing unit configured to perform printing based on the printing image data.
