Yes. Some old DEC system (RT-11?) had a 'runoff' print command, so
Unix got nroff(1) (new runoff) and troff(1) (typesetter runoff); man(1)
pages were written and stored using the markup for those, with a
manuals-specific macro package.

The online stuff, which had to display on a dumb terminal with quite
limited facilities, was generated with nroff and the printed manuals
got better formatting via troff, but both came from the same source.
