These are escape sequences meaningful to a Teletype Model 37, I think
those are half-line up/down or something like that.

Use the -T option to nroff to specify a more appropriate output device,
see the manual. It's also not very hard to write a post-processor to
simulate the 37 on most any reasonable cheap printer, I've done it a
few times in the distant past, essentially if((c = getchar()) == ESC)
switch(c = getchar()) and then do whatever is necessary (:-). See the
'col' man page (and col sources if you have them.)
