One of my exes was really into making clothing. I learnt second hand (via venting) how difficult it is to get a printer to print 1cm=1cm accurately when you buy a “pattern” (basically a tracing you follow to chop up the fabric).
They would check every printout, and half the time they had to print the same thing multiple times because the printer decided to be stupid and add a half centimetre here or there or subtly stretch it; which matters a lot for a good fit. It was a whole big thing, apparently. At least for cheap printers.
Usually it’s not the printer head that is the problem. Fabric that moves or stretches or shrinks is however a problem. (yes the printer should be tracking that. Good luck with that.)
Maybe someone hit the 110% size on a copy machine?
But the squares that are supposed to be a cm and the ruler below it are printed on the same page, they scale together.
At least it looks like a printed ruler to me.
The ruler is very clearly cut out from a different sheet.
That’d be my guess. Lot of potential scaling issues in print.

They printed on paper to later re-trace the shape on fabric manually
It’s a bound textbook!
Eh, could also just be ‘assume each box is 1 cm’ without intending to be accurate.
Now if they said use a ruler to figure it out and they claimed it’s 10 then there’s an issue where someone needs a new tool
