Displaying a preview image is improved. An image processing device that displays on a display a preview image of printing a print job has a controller configured that acquires the printing order of multiple image layers included in the print job, generates a preview image overlaying the multiple image layers according to the acquired printing order, and displays the generated preview image on the display. The controller displays on the display an input field for receiving an instruction specifying the printing order of the multiple image layers, and acquires the printing order by receiving the instruction through the input field.
