Windowing: Setting Up Soft-Clip Limits
Soft-clip limits temporarily restrict pen movement to a rectangular
area, or window. When you initialize or set the printer to default
conditions, the soft-clip limits are the same as the PCL Picture
Frame limits.
To create a window, you use the Input Window (IW) command.
The printer does not draw outside the window.
The following illustration shows the four types of line segments you
can specify from one point to another.
