Abstract: A method of printing a document using one of a plurality of print modes, the method comprising: (i) notionally dividing a digital image of the document into sectors; (ii) for each sector, comparing one or more properties of the luminosity of pixels within each sector with one or more threshold values; (iii) using the comparison of (ii) to determine whether each sector is likely to show an image defect if printed at a lower image quality print mode; (iv) selecting a print mode such that all sectors are determined not to be likely to show an image defect; (v) printing the document using the determined print mode.

Abstract: A printing method and system include a printhead configured to eject a fixer fluid. A controller is operatively connected to the printhead and configured to control the printhead so as to apply the fixer fluid to a print area in a pattern to form cells having a predetermined area without the fixer fluid.

Abstract: A printing method and system include a printhead configured to eject a fixer fluid. A controller is operatively connected to the printhead and configured to control the printhead so as to apply the fixer fluid to a print area in a pattern to form cells having a predetermined area without the fixer fluid.
