groff's nroff here, which has a page length of 66 lines using -man,
doesn't insert a formfeed character anywhere.  It just puts the right
number of blank lines in, knowing that the printer will move onto the
next sheet after 66 lines.

The first output shows no formfeed character.

    $ echo abc/.bp/def | tr / \\012 | nroff -man | od -c
    0000000   a   b   c  \n  \n  \n  \n  \n  \n  \n  \n  \n  \n  \n  \n  \n
    0000020  \n  \n  \n  \n  \n  \n  \n  \n  \n  \n  \n  \n  \n  \n  \n  \n
    *
    0000100  \n  \n  \n  \n  \n   d   e   f  \n  \n  \n  \n  \n  \n  \n  \n
    0000120  \n  \n  \n  \n  \n  \n  \n  \n  \n  \n  \n  \n  \n  \n  \n  \n
    *
    0000200  \n  \n  \n  \n  \n  \n  \n  \n  \n  \n
    0000212

The second the number of lines per page.

    $ echo abc/.bp/def | tr / \\012 | nroff -man | uniq -c
          1 abc
         65
          1 def
         65

Can you show us some sample input, how you process it, and what comes
out, and someone may have a better idea than I.

Cheers,


Ralph.
