ABSTRACT:
A sheet transport for a printer moves the leading edge of a sheet along a short and substantially straight path while inverting the sheet side-to-side. An output path feeds back to the printer input so a second side is printed in the correct orientation. Preferably a non-inverting sheet transport feeds directly into the output path, so that a once-printed sheet is transported to another printer, or is returned to the printer for a second pass either inverted, or on the same side. A deflector curls the sheet over a bar onto a transport at a different level, and as the paper advances, its trailing edge is drawn over the bar, flipping the sheet over.
