It depends on the surface: glossy; pearl; matte; textured.

The paper: resin coated; fiber base;

And how it is dried: ferrotyped (FB); or air dried (FB + RC)

But, for practical purposes, not an issue.

Examined under a 30x microscope pearl finish RC and air-dry
fiber glossy paper show sharply delineated dust motes.

Mote feature size is ~0.02mm.

My WAG is greater than 100 lp/mm.

The old glossy textured papers - sort of very fine grain
car-dashboard texture - looked to have less resolution
because of the distortions of the texture.

Matte papers also appear to have less resolution but
the effect may be due to lower paper contrast.

Any paper effect will by psycho-optical: surface finish,
lighting, glass over the print, AR coatings, blood
pressure, blood sugar, fatigue, jostling crowd, subject
matter, myopia, astigmatism, sheer bloody mindedness ...

It should be pretty high, since its speed is low compared with most films.
In photo paper, you would need around 10 line-pairs per millimeter to exceed
that of the human eye, but I imagine the paper is better than that. It would
depend on the surface, the contrast, etc., of  course.

Where I work (www.appliedimage.com)   we make resolution charts and
other precision patterns. We like to limit the pattern to 18 or 20 c/mm
(on white reflective photo paper) because visual degradation below this
becomes apparent. You can get some sort of image down to about 50 c/mm
but the contrast is very low.
