Provided are: a holding unit configured to rotatably hold a roll body on which a medium is wound; a transport unit configured to transport the medium unwound from the roll body; a tension applying unit configured to press the medium between the holding unit and the transport unit to apply tension to the medium; a driving portion configured to provide driving force to the tension applying unit; a control unit configured to control the transport unit and the driving portion; and a detector configured to detect a load applied to the transport unit, and the control unit controls the driving force by the driving portion on the basis of the load detected by the detector to adjust the tension applied to the medium.

Method for controlling a web in a printing apparatus

A method is provided for controlling a web in a printing apparatus The printing apparatus includes a transport assembly for moving the web through a transport path along a printing unit for printing an image onto a print area of the web. The method includes feeding the web from a supply roll through the transport path to the transport assembly; and switching the printing apparatus to a ready-to-print mode, wherein the printing unit does not print an image on the web and the web is maintained ready to be printed on. In a printing mode after the ready-to print mode, the following steps are performed: moving the web through the transport path in a transport direction along the printing unit by the transport assembly; and printing the image onto the print area of the web by the printing unit. The image is printed by applying an image material, which solidifies on the web during the printing step. The ready-to-print mode includes the step of: operating the transport assembly to prevent a deformation of the print area of the web in the transport path, while maintaining the web in the ready-to-print mode. The web is maintained ready to print while preventing a deformation of the print area of the web in the transport path.
