Abstract: A method of printing document data in page description language format using a plurality of graphics processing units. The plurality of tiles representing the document using the assigned graphics processing units are rendered in parallel with one another, and the rendered tiles are transmitted, bypassing the central processing units, from each of the graphics processing units to a corresponding one of a plurality of print head controllers, with the rendered tiles transmitted at a higher frequency than a frequency at which the plurality of tiles is output from each print head controller. The rendered tiles are repeatedly transmitted until each print head controller completes output of the previous band.

Abstract: A method of generating halftone print data for overlapping end portions of a pair of consecutive printhead segments in an array of two or more printhead segments is disclosed. Generally an end portion of a first printhead segment overlaps an end portion of a second printhead segment, in which each printhead segment includes a plurality of ink ejection nozzles. The method includes generating a dither value from a dither matrix, and then combining the dither value with an overlap signal, which represents an extent of overlap of the end portions, to produce an output value. A mathematical operation is then performed on continuous tone print data using a comparator, based on the output value, to produce the half tone data.

Abstract: A printer uses a dithering mask having a width that is 1/N (where N is a nonzero positive integer) times a number of pixels corresponding to the layout pitch of print head tips, so as to always have an identical positional relationship between the dithering mask and the connecting portions of the print head tips, so as to perform a half toning process and print image data. The dithering mask DM is a dithering mask that is optimized so as to be able to obtain dot dispersion characteristics that are somewhat good regardless of the positional shift patterns between the print head tips. Doing so enables the suppression of degradation of printed image quality that stems from differences in characteristics of the plurality of print heads in a line printer that performs printing using a plurality of print heads that are arrayed across a printing range. This also enables efficient half toning processing to be performed by reducing extremely the overhead in producing dithering masks that take into consideration the positional shifts between the plurality of print heads.
