Neat idea. Thanks.

Just be aware that most printers do not print exactly to scale, especially
in the long direction on the paper (i.e., the direction that is
perpendicular to the rollers in the printer), which is the direction that
matters when printing this ruler out on anything other than a printer than
can print 13" wide paper and up. So...after you print it out check it
against a ruler that is known to be good.

Actually most printers do print to scale."IF" the software instructs it to.
