1. A print engine for a printer, the print engine including:

  • a page width printhead, the printhead including an ink-ejecting means comprising a micro-electrical mechanical device defining an array of inkjet nozzles which provides photographic-quality and magazine-quality printing and a sealing means surrounding the ink-ejecting means;

    a smooth-surfaced transfer means having a discontinuity-free peripheral wall onto which ink ejected by the printhead is received to be transferred to a sheet of print media, the transfer means being arranged adjacent to the printhead; and

    a displacement means for displacing the printhead so that its sealing means is urged into abutment with a surface of the transfer means when the printhead is inoperative to inhibit evaporation of ink from the ink-ejecting means, the displacement means further being operable to draw the printhead into spaced relationship relative to the transfer means when printing is to be effected.
