Revert "Don't use the printf command; it's not guaranteed to be there."
This reverts commit 67c58497442fb52571e7507cab0115567eb6352d. It's not *guaranteed* to be there in *every* UN*X, but it's in at least the Single UNIX Specification V3, as well as in shells commonly used in non-UNIX UN*Xes :-), so it'll be there in the UN*Xes we'll be run on.
