The issue is NOT printing directly from Mathematica 6, whether to a printer or to a pdf file (nor then printing from the created pdf file). Rather the issue is solely using Export to export the single graphic to an eps file. It's that file which -- whether viewed directly in GhostView on-screen, printed from Ghostview, or incorporated into a LaTeX document and viewed/printed from there -- shows the spurious grid lines.
