A scrolling system for scrolling a printed roll of media includes a mechanical scrolling apparatus and a user interface device. The mechanical scrolling apparatus includes a first winder for placing the printed roll and from which first winder the printed roll is unwindable, and a second winder for winding up the printed roll unwound from the first winder. At least one winder of the first and second winder is drivable by a motor. An unwound area is a piece of the printed roll that is unwound from the first winder and not yet wound up on the second winder. The user interface device is configured to receive a selection of a part of a digital representation of images printed on the roll. Upon receiving a selection of the part of the digital representation of the images printed on the roll by means of the user interface device, the motor is activated in order to scroll the printed roll by means of the two winders until a piece of the printed roll arrives in the unwound area, which piece of the printed roll corresponds to the selected part of the digital representation. A method to be applied by the scrolling system is also disclosed.
