Abstract
A print media roll holder includes a multi-diameter core adapter for mounting print media rolls of different core sizes. The roll holder comprises a ring-shaped frame having a base portion provided with a guide rack which is used for positional adjustment. The multi-diameter core adapter is pivotally mounted inside the ring-shaped frame on two opposing lateral pins inserted through the frame and through the core adapter for 180 degree rotation in a clockwise or counter-clockwise direction depending on the size of core being used. The guide rack is part of a rack and pinion gear system used to vary the spacing between the roll holders in a reciprocal linear fashion.
