1. A label marking device for printing selected bar code and alpha-numeric character information upon a label, said device comprising: a frame; a printing station on the frame; a supply of labels; a printing medium; a plurality of scribe elements mounted on the frame for location of selected scribe elements, corresponding to selected bar code character information, at a first location at the printing station; a plurality of print elements mounted on the frame for location of selected print elements, corresponding to selected alpha-numeric character information, at a second location at the printing station, the second location being adjacent to and spaced from the first location; pressure means mounted on the frame for placement at the first location; impact means mounted on the frame for placement at the second location; and actuating means on the frame capable of actuation through a cycle of operation for moving a label, from the supply, together with a portion of the printing medium juxtaposed with the label, between the pressure means and the selected scribe elements at the first location while urging the pressure means to press and continue to urge the juxtaposed label and printing medium against the scribe elements while the scribe elements remain stationary so as to scribe information on the label in the form of a bar code having code bars running parallel to the direction of movement of the label as a result of such movement of the label relative to the scribe elements during a first portion of said cycle, and actuating the impact means to impact the juxtaposed label and printing medium momentarily with the selected print elements at the second location so as to print information on the same label corresponding to said selected alpha-numeric characters during a second portion of said cycle.
