Abstract
A high speed printer wherein sheets of continuous forms are fed to the print station by a pin feed sprocket type mechanism drivingly engaging marginally punched holes in the sheets. Each sheet is accurately moved past the print station during print time under control of a pressure feed roll mechanism the operating characteristics of which are independent of the relative position or physical condition of the marginal holes engaged by the sprocket. This sprocket and pressure feed roll coaction results in precision alignment as among printing lines within a sheet being advanced through a high speed printer.
