Abstract: An inked ribbon assembly for use with a printing apparatus such as a thermal facsimile machine includes a generally cylindrical supply spool, a generally cylindrical take-up spool, and a sheet-like inked ribbon extending therebetween, with the inked ribbon rolled upon the supply spool and connected to the take-up spool for advancement through the printing apparatus to the take-up spool. The spools of the inked ribbon assembly are rotatably supported in the printing apparatus by support spindles, which effect driven rotation of the supply and take-up spools. The support spindles each include one or more drive lugs which engage the spools of the ribbon assembly for effecting advancement of the inked ribbon.
