   This is a general problem not confined to troff.  So don't assume that

Not true - The format output for TeX/LaTeX, DVI, was designed to be
device independent. An TeX has an internal fixed-point rational math
library used to insure *exactly* the same results on different
devices, at least as far as placement goes.  In fact, you can't call a
TeX implementation `TeX' unless it passes something called the ``trip
test'' that insures that your implementation matches others.

The only variability is in fonts & device resolution. You can run with
blacker/darker fonts & it'll look slightly different.
