They're all CM fonts.​

This is a real shot in the dark, but here goes:

​I guess I can try putting
\XeTeXinputnormalization=1
\tracinglostchars=1
\tracingonline=1​
​into the preliminaries.  I just got the TeX files a few hours ago, so when
I have time, I'll have a look at the code, and see whether processing on my
machine makes any difference.

Meanwhile, I'm at home now, and I've just printed out that page kkk.pdf
that I sent around, and it works just fine on my Epson WF-3640.  The HP
printer/driver is looking more and more guilty.
