We have two proof planers (or “planing blocks,” one large and one small), and one wooden mallet.  These are used in planing type–that is, leveling the type in the form (i.e., the term for set page(s) locked in and ready for printing) to make sure that it is standing on its feet.  If one letter is the least bit higher than the others on the bed, it will foul the impression. It is fascinating to me how much precision is required in every aspect of printing.  Think of this the next time you blithely press the print icon on your computer–in less than a second, you can accomplish what it took past generations years to produce.
