Printer incorporating opposed printhead assemblies

1. 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.

2. A printer as claimed in claim 1 , wherein said array consists of a one dimensional array.

3. A printer as claimed in claim 1 , wherein the air displacement mechanism includes an air pump in fluid communication with the expulsion nozzles.
