HP PCL 5 - Raster Graphics Command Sequence

15-4 Raster Graphics EN
Raster Graphics Command Sequence
PCL raster commands include: Start Raster Graphics and End Raster
Graphics commands, Transfer Raster Data by Row, Raster
Compression, Raster Presentation, Raster Resolution, Raster Height
and Raster Width (which define the raster area), and Raster Y Offset
commands. The normal sequence of execution for these commands
is shown below:
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.
