A ribbon cartridge and drive system for use in printers, typewriters, copiers or the like in which a supply spool and a take-up spool are enclosed in a housing with each spool extending from the housing for selective alternate engagement with a drive member connected to a brake member, both being coordinated with the movement of a printing head. A stripper bar peels the ribbon from a copy sheet downstream of printing head movement. The drive system cooperates with the printing head whereby a method of ribbon conservation is realized.
