CHAPTER 4: COMMAND SEQUENCE 
 
4.1 Raster Graphics Modes 
 
The following three modes are available for raster graphics commands: 
1)    Non-compressed mode - the print data is transferred without being compressed. 
Effective for printing data with a low compression ratio, such as photographs. 
2)    Run-length encoded mode - the print data is transmitted after run-length encoding compression. 
Effective for printing data such as graphs and figures, in which patterns appear repeatedly. 
3)    TIFF compressed mode - the print data is transferred after TIFF compression. 
Effective for printing data such as graphs and figures, in which patterns appear repeatedly.
