An endless tape for an impact printer is provided with separate groups of flexible fingers which project laterally from and along one side edge of the tape. The fingers of each groups are formed integrally with a common base and the base is removably attached in face-to-face relation to the tape. The ''''grain'''' of the material of the tape extends longitudinally of the tape in order most effectively to resist tape breakage due to the flexing of the tape as it is travelled along its endless path, whereas the grain of the material of the groups of fingers extends longitudinally of the fingers likewise to maximize their lives incidental to the flexing of these fingers caused by the striking hammers.
