I believe IDL 3.6.1 has a flag on the SHADE_SURF command
specifically for avoiding these problems with PostScript
printers. But you're using PV~WAVE...

I use the Z buffer and set the Z buffer size to obtain 300dpi pixels
on our dye-sub printer.
1. Setup Z buffer with approriate x and y sizes
2. Plot to the Z buffer.
3. Read the contents of the Z buffer as a image.
4. Plot the image to the Postscript device with appropriate x and y
sizes.
I really wish that the user could specify the image dimension of the
shaded surface directly for the Postscript driver. The current
situation is not good.
