Ink jet swath prediction method
摘要:
A method of positioning an ink jet printhead in a printer includes dividing a bitmap into a plurality of rows of tiles. A subset of the rows of tiles to be printed in a next pass of the printhead is identified. Printable ones of the tiles in the subset of rows are identified. The printable tiles contain printable data. Within each printable tile, a top most location of the printable data and at least one of a left most location of the printable data and a right most location of the printable data are identified. A print medium is advanced in a feed direction until a portion of the print medium corresponding with the top most location of the printable data of at least one printable tile is substantially aligned with a top nozzle of the printhead. The printhead is moved, in a scan direction, directly to a position on the print medium corresponding to one of the left most location of the printable data of at least one printable tile and the right most location of the printable data of at least one printable tile.
