When you turn on the printer, the window is automatically set to the PCL Picture Frame boundaries. You can define a window that extends beyond the picture frame, however the printer cannot print vector graphics beyond the effective window. All programmed pen motion is restricted to this area. For more information, refer to “Windowing: Setting Up Soft-Clip Limits” at the beginning of this chapter.

Figure 19-12The Effective Window

If the window falls entirely outside of the PCL Picture Frame, no image is drawn. The IW command remains in effect until another IW command is executed, or the printer is initialized or set to default conditions.

The following example draws a label, then establishes a window and again draws the label along with a line. Notice how the line and label are clipped after the window is established, but not before.
