Utility which calculated page coverage for printing?

[OliverScott]

What would be nice is somthing (possibly a fake printer driver?) which works out the page coverage for black and colour for print jobs and possibly even calculates the cost of the print job if given the cost of toners, fixed life components (fuser units etc), and media...

Does such a utility exist?

Would be interesting seeing as toner for the printer in work is £170 for each colour!
