HP L 5 manual Emphasis in the previous command sequence is that the Raster

	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.
