If n = 5 has been selected, you will need the following command.
<ESC>*v n T
This command selects the current pattern type to be applied to source images
(not rectangular areas) before printing.
n Value
Pattern
0 Mm)
Solid black
1
Solid white
2
Currently defined shading pattern
4 Currently defined cross-hatched pattern
For n = 2 or 3, the pattern defined by the most recent <ESC>*c n G command
is used. To change the pattern, a new aSC>*c n G and a new <ESe>*v n
T command are needed.
The following two commands control “transparency”, whether or not white
sections of an image block out black pixels that are already in place.
<ESC>*v n N
This selects the source transparency mode, whether white areas of the source
image should be treated as transparent (and do not “white-out” black pixels
they cover) or opaque (in which case they white-out black pixels).
Set n to 0 for the transparent mode and to 1 for the opaque mode.
<ESC>*v n 0
This selects the pattern transparency mode, similarly to the above command,
whether the current pattern should be treated as transparent or opaque.
Set n to 0 for the transparent mode and to 1 for the opaque mode.
Examples: Pattern graphics
To specify a block five inches wide you could use a horizontal dimension of
1500 dots (5 inches times 300 dots). That command would look like this:
<ES0 *c 1500A
To print that area with a 25 percent gray-scale pattern, the commands you
send would be:
<ESC> *c 25G
<ES0 *c 2P
