You did not say, but I surmise that you are using the ms(7) package.
(man(7) also has a `PP` macro, but does not behave the same way.)

Yes, if you use a low-level request like this.  groff ms(7) supports the
`FAM` string to persistently change the font family, starting at the
next paragraph.[1]  This is documented in groff_ms(7) and (in the
forthcoming 1.23.0) the ms.ms document.

If you have read my unfortunate exchanges with Christof Meerwald, you
know how I feel about the use of low-level requests when a macro package
provides a facility for accomplishing the same objective.[2]

I'm thrilled to hear that this is working well, and will work better for
more people as soon as we can release!

Regards,
Branden
