A printing device for printing substrates, such as circuit boards, wafers, or solar cells, has at least one movably mounted printing unit with a working surface on which the substrate to be printed can be placed. The printing unit is paired with a transport belt device, which has a supply roller with a transport belt wound thereon, a collection roller for winding up the transport belt, and two deflecting surfaces, in particular deflecting rollers, which are paired with the working surface. The transport belt is guided by the supply roller over one deflecting surface and onto the working surface in order to form a contact surface for the substrates, and by the working surface over the other deflecting surface to the collection roller. The deflecting surfaces can be moved together with the respective printing unit. The supply and collection rollers are held on the printing device in a stationary manner.
