Abstract
A matrix printer with a reciprocating carriage carries transversely moving spring biased printing head. A roller on the head runs on a resilient rail urged against the platen and can be retracted by pivoting the rail carrier under engagement of a second rail cooperating with a second roller on the head. A cam track in a terminal position of the carriage provides for independent head retraction through engagement with the second roller.
