Abstract
A spool, such as supply for a wide-format printer, is provided. The spool comprises a spindle for slidingly receiving an outer shaft, which is typically the core of a roll of print media. A first resiliently deformable gripping ring is circumferentially mounted about the spindle, and a compression mechanism is provided for axially compressing the gripping ring. The axial compression causes radial expansion of the gripping ring, thereby urging the gripping ring into gripping engagement with the outer shaft received on the spindle.
