User-Defined Pattern Graphics
In addition to the eight shading patterns and six cross-hatch patterns,
users can design their own fill patterns. These user-defined patterns
are downloaded to the printer and controlled using three commands:
• Download Pattern
?*c#W [data]
• Set Pattern Reference Point
?*p#R
• Pattern Control
?*p#Q
Using User-Defined Patterns
To create a new pattern, a user defines a binary raster data image as
a base pattern. This base pattern is downloaded to the printer using
the User-Defined Pattern command. Prior to downloading the pattern,
a Pattern ID command is sent to assign the user pattern an ID
number. This ID number is used to select the pattern for printing and
for pattern management.
To apply the pattern to an image, the printer duplicates or tiles (like
placing ceramic tiles) the pattern across and down the page. This
pattern can be applied to any image, including rectangular area fill.
Figure 5-9 User-Defined Base Pattern Example
A user-defined pattern may be applied to any image in the same
manner as the internal cross-hatch or shade patterns.
