It's on the 1981 Usenix tape, in the ucol directory:

It looks like leroy produces output for an "extended" form of plot; from
the docs:
--
     The plot stream leroy emits is intended for,  and  must
be directed to, an extended UNIX plot filter.  These filters
recognize a number of commands not included in  the  vanilla
seventh  edition  filters,  mostly  dealing with the Hershey
fonts.  The extended plot filters are upward compatible with
their  predecessors  and  have been implemented in a fashion
which makes tailoring new devices filters very  straightfor-
ward.   The  source  code  is available on request.  Filters
currently exist for the Tektronix 4014,  the  Versatec,  the
HP7221A, and the Qume.
