A printing device or coder particularly adaptable for printing data on each of a plurality of articles such as conveyed in a moving production line. The device comprises a holder for preselected type mounted on a rotatable shaft connected through a slip clutch and a drive means to a rotary power means. The drive means is also connected to an ink roll positioned near to the type holder shaft. A pawl, normally urged into engagement with a cam member, holds the type holder in one position as the holder's shaft is allowed to slip momentarily with the clutch and as the type engages an article being printed. Thereafter, a movable trigger disengages the pawl and cam member and releases the type holder, allowing it to rotate into contact with the ink roll during one revolution of the shaft prior to the next printing cycle.
