I think that we discussed this at some stage and found that it was not
clear that we could come up with a single value. For example, depending on
the type of printer, the speed is often dependent on whether you run in
"draft" mode vs. "quality" mode, and whether you run B/W or color. So we
would have ended up with some kind of conditions and several values to
cover all cases.
