A printing device includes a first printer and a second printer which continuously print one or plural pieces of printing data onto a printing medium. In the printing device, the second printer includes a reading sensor, the first printer first prints the one or plural pieces of printing data onto the printing medium by forming a mark indicating a page of the printing medium or each of the plural pieces of the printing data, the reading sensor in the second printer subsequently reads the mark and matches printing surfaces of the printing medium to be printed by the first and second printers, and the second printer thereafter prints the printing data onto the printing medium. The printing device includes an information holding part which previously holds information on a relationship between the mark position and a size of the printing medium or a size of each of the plural pieces of printing data, and a mark position setting part which movably sets the mark position based on the information held in the information holding part in accordance with the size of the printing medium or the size of each of the plural pieces of printing data.
