The emphasis in the previous command sequence is that the Raster
Presentation Mode, Raster Resolution, Raster Height, and Raster
Width are all set outside the start..data..end sequence of commands.
Also, the entire image is sent during the start..data..end sequence,
choosing the most effective compression method for each raster row
of data.
Raster Presentation, Raster Resolution, Raster Height, Raster Width,
and Raster Compression are all true modes. Once specified, the
printer remains in that mode unless explicitly changed by issuing the
command again, or reset to default values by a soft reset, self test,
font printout, or power cycle.
Note Only raster data appearing within the intersection of the logical page,
the printable area, the raster width, and height is printed. If raster
width and/or raster height have not been set, the intersection of the
logical page and the printable area determines where raster graphics
appear; raster data is clipped to the printable area.
