DESIGN2003 css and tableview Printing window.print()

Question

When I print a page rendered using basic TABLEVIEW htmlb tags, I was disappointed to see that output looks a bit ugly.
The table header row and data rows do not have a separating lines as the data rows have.
The online view is ok since the header is shaded differently. But when printing black on white you dont see the header and data row separation.
Did I miss something, or is the default style sheet not
catering well to printing.
Has someone modified the standard css design2003 to print
differently ?
Is there a simple solution to this output window.print()
issue.
regards
Phil.

Thanks Max,
I was unaware of this feature.
It is locked down at the customer Im at anyway.
But good to know for next time.
I was hoping SAP may have, or someone else may have,
altered the CSS to print differently.
Ie with a table frame rather than rely on shading which
still may be interpreted as white by some black and white printers. I know grey scaling is good on many new printers. 
I also expected that exactly this issue had been addressed by just about all uses of tableview before me.
Im surprised that there seems to be no "nice" solution.
Is everyone else happy with the way tableviews print ?
What are you all doing to make print output look good?
Cheers
Phil.
