Abstract:
1. A spool for a printer, said spool comprising: a spindle for slidingly receiving an outer shaft, said spindle having first and second ends; and a first resiliently deformable gripping ring circumferentially mounted about a first end of said spindle; a second resiliently deformable gripping ring circumferentially mounted about an opposite second end of said spindle; and a compression mechanism for axially compressing said first and second gripping rings simultaneously, said compression mechanism comprising: wherein one end of said roll of print media is urged against said reation end-plate by said thrust end-plate thrusting against an opposite end of said roll of print media, thereby causing said telescopic expansion, and wherein said axial compression causes radial expansion of said gripping rings, thereby urging said gripping rings into gripping engagement with said outer shaft received on said spindle.
