ABSTRACT:
A printer comprising: a support structure; a feed arrangement positioned on the support structure and configured to feed an endmost sheet of print media from the stack and including a movable pick-up assembly, the pick-up assembly having an array of spaced apart nozzles configured to direct air on to respective locations along said topmost sheet so that said topmost sheet can be picked-up from the stack by moving said pick-up assembly; a pair of rollers configured to engage with said endmost sheet fed from said feed arrangement; a printing station configured to print ink upon said endmost sheet engaged by said rollers; and an air displacement mechanism connected to the nozzles to displace air out of some expulsion nozzles and into some other suction nozzles, wherein said printing station has a pair of opposed printhead assemblies between which said endmost sheet can be fed so that concurrent duplex printing can be performed on the endmost sheet.
