Set Pattern Reference Point Command
The Set Pattern Reference Point command causes the printer to tile
patterns with respect to the current cursor position. This command
also specifies whether the pattern rotates with the print direction or
remains fixed.
E
C
* p # R
# =0 - Rotate patterns with print direction
1 - Keep patterns fixed
Default = 0
Range = 0,1 (values outside the range are ignored)
A value field of 0 rotates the patterns with changes in the print
direction (see Print Direction command). For a value field of 1,
patterns remain fixed for changes in print direction.
The default pattern reference point is the upper left corner of the
logical page at the top margin (position 0,0). If the Set Pattern
Reference Point command is not set, the pattern is tiled with
respect to the default reference point.
Notes All patterns are rotated for changes in orientation (refer to “Logical
Page Orientation Command” in Chapter 5 of this manual).
This command applies to user-defined, shading, and cross-hatch
patterns.
