A display system (100,200) configured to display a print preview of a roll paper image and a print area includes an acquisition unit configured to acquire a roll paper width (S1,S2,S3), and a horizontal length of a set paper size, a print-area determination unit for determining a print area based on the acquired roll paper width and horizontal length (S4,S12), a determination unit configured to determine whether the determined print area is displayable in a preview area (S5), a calculation unit configured to calculate a scaling required to display the entire print area in a preview according to a vertical length of the print area (S6), and a display control unit configured to, if it is determined by the determination unit that not the entire print area is displayable, preview a roll paper image and a print area based on the scaling calculated by the calculation unit (S7). |
