A machine particularly adapted for printing card stock. A head or carriage is mounted to reciprocate over a type bed. The carriage mounts the impression roller, inking rollers, doctor roller and an oscillating roller. The impression roller is mounted on an adjustable eccentric shaft adjustable to compensate for different thicknesses of card stock to thereby control the printing pressure. The impression roller is driven through roller members that move on rails which are coupled by way of a positive clutch to the ends of the impression roller which is positively driven in any adjusted position. The inking rollers, oscillating and doctor roller are mounted between side plates of the carriage, improved means being provided for lifting the inking rollers and for lifting the oscillating roller and doctor roller.
