CHAPTER 5: COMMAND SEQUENCE FLOW
5.1 Raster Graphics Mode
The Raster graphics command controls the following two modes.
1) Non-compressed mode Print data are transferred without compression. This is effective
especially for photographs and other data, which yield only a low
compression ratio.
2) RLL compression mode Print data are compressed using RLL (run-length limited)
compression. This is effective for data with repeated patterns, such
as graphics and illustrations.
