In my local Staples it said 6.5p for a page with 20% coverage.

Does this sound right?

It was a Konica Minolta 2400 for which I always thought the cost per page
figures quoted were for 5% coverage - a quarter of the Staples statement.

They probably mean 5% of black, cyan, magenta and yellow which makes 20%.

The figure of 6.5p seems quite low, I just did a quick calculation and got
it to around 7.8p + VAT.

These calculations are never very accurate because they are based on the
manufacturers stated life of the consumables which always achieved in
optimum conditions not in real life.

Staples gave you the 5% coverage figure at 5% for each colour, and since
there are four colours, quoted 20% coverage. This is nonsense IMO, but
common. The correct quote IMO should be "at 5% coverage, using all four
colours." But what that means in terms of coverage for each colour is
another question. 5% coverage is 12 pt text double spaced with approx.
2cm margin on an A4 or 8-1/2x11 page -- or so it was described to me
once, when I asked. If you use coloured text, obviously you still have
5% coverage, just a different combination of inks.

For black (single colour) printing the 5% coverage standard is well
established, and works if accompanied by qualifiers such as "at letter
quality printing." It's also related to the real world, since a typical
business letter with letterhead amounts to about 5% coverage. (Note that
this standard refers to the amount of space taken up by each character,
_not_ to the amount of space taken by the ink dots, which is another
issue, see below.)

20% coverage would be a strip about 12cm wide from one edge of the page
to the other. What this means in terms of % coverage in terms of ink is
something else again. It depends on whether the inks are layered, or
printed next to each other (like the pixels on a screen), or partly
overlapping, or spaced apart. That's a matter of printer technology and
printing quality. I've been told that different printers lay down the
ink or toner differently.

Then there is the issue of draft vs high-quality printing. Draft
printing will use as little as one quarter of the ink used by HQ
printing - which means than "coverage" is less for the same size image
or typeface. These considerations make "x% coverage" a term with little
relation to the real world use when it comes to colour printing.

IMO, colour printing costs should be based on full colour, HQ 4" x 6"
(10cm x 15cm) prints. Not that I insist on this size - I just want a
common base of comparison. "x% coverage" is not good enough for colour
printing.
