A sheet feeding, registering and printing apparatus has one or more printing units for printing desired characters on a sheet, and means for feeding such a sheet positively to and from a printing position with respect to each printing unit. The feeding means includes a feed band having gripping devices for gripping engagement with each sheet to hold the sheet in a predetermined position on the band, with no longitudinal slippage. The band is driven intermittently in equal incremental movements to and beyond the printing position. The apparatus includes initial sheet supply mechanism for feeding successive sheets to the band, and registration means for sequentially positioning a leading edge of each sheet in accurate registration with the band and for engaging the gripping devices with the sheet before the sheet is moved intermittently to the printing position.
