HP PCL/PJL reference (PCL 5 Color) - Technical Reference Manual

6-6 Raster Graphics EN
Raster Graphics Command Sequence
PCL raster commands include: Start Raster Graphics and End Raster
Graphics commands, Transfer Raster Data by Plane and Row, Raster
Compression, Raster Presentation, Raster Resolution, Raster Height
and Raster Width (which define the raster area), and Raster Y Offset
commands. For printing well-behaved raster graphics, the normal
sequence of execution for these commands is shown below.
Hewlett-Packard strongly recommends that developers use this
command sequence in their applications.
Note Although the source raster height and width commands are not
necessary, they improve memory efficiency.
