Polygonal Viewport printing problem

when I have a Polygonal Viewport in a drawing and try to print it, the print never comes out correctly, bits and pieces are missing but if i turn the same drawing into a normal rectangle viewport the problem disappears. I'm using AutoCAD 2005 and i have never had this problem with any other version of Cad. Any thoughts?

 

This is a bug in the software. When you use a rectangular viewport - the
time honored tradition, AutoCAD sends only the geometry that fits in the
viewport to the device. Lines, text, circles, etc. that are outside the
visible rectangle never get sent. By honing this process over years of
operation, the printout looks right - just as it appears on the screen.
Nonrectngular viewports are a relatively new to AutoCAD. For a device to be
able to handle this, all of the geometry in the viewport needs to be sent to
the device. The clipping capability of the device is then used to cut away,
not print, the geometry that is outside the viewport. My guess is that the
clipping code on the printer driver is cutting away too much which is why
bits and pieces are missing. With a rectangular viewport, the clipping
portion of the printer driver doesn't come into play. (Clipping is still
used, it is just set to a rectangle, which is knows how to do well.)
