CHAPTER 5 COMMAND SEQUENCE FLOW
5.1 Raster Graphics Modes
The following three compression modes are available for raster graphics commands:
1) Non-compressed mode The print data is transferred without compression. This method is
especially effective for printing data with low compression ratio,
such as photographs.
2) RLL compression mode The print data is compressed using RLL (run-length limited) data
compression. This method is especially effective for data with
repeated patterns, such as graphics and illustrations.
3) TIFF compression mode The print data is compressed using TIFF (Tagged Image File
Format) compression. This method is also especially effective for
data with repeated patterns, such as graphs, figures and
illustrations.
In addition, programmers may wish to utilize the roll paper mode.
