It wants the math support of latex in an html document generated from the markdown source file.
I had better sources at some point but I'll have to dig them up.
Most printers start at 300--600 DPI, before ink and/or toner bleed. 1200 DPI is photo-print level.
Serif at ~150+ DPI is both readable and preferable to sans IME.
Your referenced blog entry makes no mention of DPI that I find. And makes numerous grammatical choices which lead me to question its authority.
For printer DPI comparisons see: https://www.printerknowledge.com/threads/effective-print-out...
However, I don't know if there's a way to use it for regular Tex documents.
This does use KaTeX for rendering the TeX:
> Math support is the core functionality of mdmath. Inline math $r = \sqrt{x^2 + y^2}$ and display math expressions $$e^{ix}=\cos x + i\sin x$$ are supported, due to markdown-it extension markdown-it-texmath [8] and the fast math renderer KaTeX [9].
