Abstract
In a method or device to dry a web-shaped recording medium in a printer, the web-shaped recording medium is printed with aqueous ink and subsequently directed with a predetermined web tension past a heatable body whose contact surface that faces towards the recording medium is brought into contact with a side of said recording medium that has not been freshly printed to dry said recording medium in a drying operation. A first guide element is arranged before the heatable body and a second guide element is arranged after the heatable body, the first and second guide elements guiding the recording medium. The contact surface of the heatable body is substantially flat. A negative pressure device generates a negative pressure at the contact surface facing towards the recording medium. The negative pressure is deactivated in a halt operation, the deactivation process taking place continuously over an adjustable time interval.
