Printing system for web media, comprising: - a transport path for transporting a web medium from a take-out roller to a take-up roller; - a buffer region positioned below the transport path for allowing the web medium to curve away from the transport path in the downward direction; - a pressing device moveable along a guide between: - a first position positioned above the transport path; and - a second position positioned below the transport path in an upper zone of the buffer region, such that movement of the pressing device from the first position to the second position presses the web medium from the transport path into an initial curve in the upper zone in the buffer region; - a locking device for holding the pressing device at the second position on the guide; - a transport system for moving the medium along the transport path, such that the initial curve of the medium at the pressing device in the second position is expanded away from the pressing device in the second position downwards into the buffer region for forming a blouse section in the web medium in a lower zone of the buffer region; a controller configured for: in a first print mode, with the pressing device in the first position, forming a blouse in the web medium by feeding web medium from the take-out roller into the buffer region, in a second print mode, with the pressing device in the second position, expanding the initial curve into a blouse by feeding web medium from the take-out roller into the buffer region, and in a third print mode, with the pressing device in the third position, transporting a web medium under tension from the take-out roller to the take-up roller; characterized in that the controller is further configured for: - receiving a print job comprising media type information; - determining whether the medium indicated in the media type information is unsuited for blouse formation in the first print mode; and - selecting the second print mode for media types determined to be unsuited for blouse formation in the first print mode. - a transport path for transporting a web medium from a take-out roller to a take-up roller; - a buffer region positioned below the transport path for allowing the web medium to curve away from the transport path in the downward direction; - a pressing device moveable along a guide between: - a first position positioned above the transport path; and - a second position positioned below the transport path in an upper zone of the buffer region, such that movement of the pressing device from the first position to the second position presses the web medium from the transport path into an initial curve in the upper zone in the buffer region; - a locking device for holding the pressing device at the second position on the guide; - a transport system for moving the medium along the transport path, such that the initial curve of the medium at the pressing device in the second position is expanded away from the pressing device in the second position downwards into the buffer region for forming a blouse section in the web medium in a lower zone of the buffer region; a controller configured for: in a first print mode, with the pressing device in the first position, forming a blouse in the web medium by feeding web medium from the take-out roller into the buffer region, in a second print mode, with the pressing device in the second position, expanding the initial curve into a blouse by feeding web medium from the take-out roller into the buffer region, and in a third print mode, with the pressing device in the third position, transporting a web medium under tension from the take-out roller to the take-up roller; characterized in that the controller is further configured for: - receiving a print job comprising media type information; - determining whether the medium indicated in the media type information is unsuited for blouse formation in the first print mode; and - selecting the second print mode for media types determined to be unsuited for blouse formation in the first print mode. - receiving a print job comprising media type information; - determining whether the medium indicated in the media type information is unsuited for blouse formation in the first print mode; and - selecting the second print mode for media types determined to be unsuited for blouse formation in the first print mode.
