Two kinds of graphics printing are possible: bit-image and raster graphics.
Although both types of graphics are based on bits in the data bytes, the
relationship between the data order and dot printing differs.
Bit Image
Bit-image graphics was developed with the layout of the print head in mind.
Data is organized to correspond to columns of print head output. Printing
takes place after each complete line is sent.
Bit-image graphics can be mixed with text printing.
Bit-image graphics is available on all printers.
Raster Graphics
Raster graphics treats data in essentially the same way as video displays and
laser printers. Data is sent in one-dot high lines. The printer reorganizes the
data internally to correspond to the print head layout. Printing may not take
place at the end of the line.
There are two levels of raster graphics: standard and extended. Standard
raster graphics is available only on ESC/P 2 printers. Extended raster
graphics is available only on the Stylus COLOR and later high-resolution
ESC/P 2 printer models.
Standard raster graphics has a special data compression feature that allows
you to economize on the data necessary to print graphics. Extended raster
graphics provides two additional data compression schemes.
Text and raster graphics printing cannot be combined on the same page.
The illustrations below show the difference between raster and bit-image data
processing.
