ABSTRACT:
A printer wherein a print head is movable by a head release mechanism, between a printing position and a release position, and a print ribbon is fed only when the print head is in the printing position. The printer has a space commanding member such as a space key adapted to feed the print head to provide a single space, when the space commanding member is momentarily operated, and feed the print head continuously to provide successive spaces while the space commanding member is held operated. The printer has a head-release control device which inhibits the head release mechanism from operating to move the print head to the release position if the space commanding member is momentarily operated, and activates the head release mechanism to move the print head to the release position if the space commanding member is operated continuously.
