Abstract: An endless ribbon for a wire matrix printer is pulled past the print head as the print head moves along the print line by a feed roll located at the entrance to a cassette which has an elongated gradually-expanding storage chamber which readily permits random folding of the ribbon in the chamber resulting in reduced ribbon tension and more uniform ribbon feed.
