Abstract
A lightweight, extremely compact printer apparatus has a constant speed drive which imparts reversible, translatory motion to a print head; and as the print head is advanced with respect to a platen imparts a direct mechanical drive to a paper advancing roller in order to advance paper from a feed roll line by line between printing operations. In turn, advancement of the paper or other recording medium from the paper roll drives a print ribbon supply holder to advance a print ribbon across the platen in front of the paper. The power requirements and size of the apparatus are substantially reduced to the extent that the apparatus is of a size corresponding to hand held calculator printers, since the movement of each element is utilized to drive another element successively from the print head carrier, paper advancement roller, paper roll to the print ribbon in close correlation to one another during each print cycle.
