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.
