Abstract

A print system for duplex printing a plurality of document page images on a plurality of copy sheets includes means for storing print control information which defines the document images. An ink jet printer prints the page images on copy sheets as they are transported past a print station by a transport arrangement defining a closed sheet path. The sheet path is of sufficient length such that a number of copy sheets are transported simultaneously therethrough. A copy sheet inverter receives copy sheets sequentially from the sheet path after the sheets are printed on their first sides and returns them to the sheet path in an inverted orientation prior to printing on the second sides of the copy sheets.
