  • Publication number: 20170136764
    Abstract: A portable large format inkjet printer for printing an image at a media print area of a stationary flat media includes an inkjet print engine having a printhead carrier system configured to dynamically scan an inkjet printhead over the media print area in each of two orthogonal directions during the printing of the image. An alignment frame is configured to fixedly mount the inkjet print engine to facilitate a manual positioning of the alignment frame and the inkjet print engine in unison. The alignment frame has an open interior window within which the inkjet printhead is moved and from which all printing occurs. At least one alignment panel is mounted to the alignment frame. Each respective alignment panel has an alignment indicia configured to facilitate accurate manual positioning of the portable large format inkjet printer at a desired printing position at the media print area.

  • Patent number: 7168785
    Abstract: A method of printing on a print medium includes using a first quantity of nozzles of a printhead to print a first set of scan lines of a plurality of scan lines at an edge of the print medium; using a second quantity of nozzles of the printhead to print a second set of scan lines of the plurality of scan lines in an interior region of the print medium; using a third quantity of nozzles to print a third set of scan lines of the plurality of scan lines to transition between the edge and the interior region, the third quantity of nozzles being greater in number than the first quantity of nozzles and less in number than the second quantity of nozzles; and printing each scan line of the plurality of scan lines forming the image with a same number of multiple passes of the printhead, regardless of the number of nozzles used for printing during a particular pass of the printhead.

  • Patent number: 6857723
    Abstract: A first method obtains a printer having a single-printhead horizontal resolution of H dpi. Dots are printed using first and second printheads in the same print pass. The first printhead is enabled and the second printhead is non-enabled during a first portion of a carrier-movement distance equal to 1/H, and the second printhead is enabled and the first printhead is non-enabled during a second non-overlapping portion of such distance. A printer and a printhead driver for performing the first method are described. A second method obtains a printer having a single-printhead resolution of H horizontal dpi by V vertical dpi. First print data for the first printhead and second print data for the second printhead of H/2 horizontal dpi by V vertical dpi are obtained, are horizontally interlaced creating H horizontal dpi by V vertical dpi, and are printed using the first and second printheads in the same print pass.
