Transfer Raster Data

Purpose The Transfer Raster Data command precedes a single row of raster graphics data. The resolution of the data has been selected through the Graphics Resolution command, and the left graphics margin defined by the Start Graphics command. The raster data is printed at the current Y position.

Raster data is always printed parallel to the feed edge of the paper, regardless of the paper or page orientation. Because the coordinate system is different for portrait and landscape pages, the positional change required to establish the start point of the next row of data is different for each orientation. On a portrait page the Y position is automatically incremented after each row of raster data. On a landscape page the X position is automatically decremented after each row.

Each byte of raster data received comprises eight bits corresponding to eight individual dots. The most significant bit is the leftmost dot. If a bit is set high, a dot is printed; if a bit is set low, no dot is printed. Each dot is expanded to the resolution specified by the Graphics Resolution command. Raster data ignores the boundaries of the text area and is unaffected by perforation skip mode.
