And options to lpr can be passed via groff's -L option, so you can say
"groff -L -o -L orientation-requested=4" or whatever.

Not in groff world!  To be militantly consistent, I suppose, in groff,
standard paper formats are always at least as long as they are wide.

groff_tmac(5) discusses the "papersize" macro file.

 papersize
        This macro file is normally loaded at start-up  by  the  troffrc
        file,  so it is seldom necessary to call it explicitly.  It pro‐
        vides an interface to set the paper size  on  the  command  line
        with the option -dpaper=size to groff or troff.  Possible values
        for size are the ISO and DIN formats “A0–A6”, “B0–B6”,  “C0–C6”,
        and  “D0–D6”;  the  U.S.  formats  “letter”, “legal”, “tabloid”,
        “ledger”, “statement”, and “executive”; and the envelope formats
        “com10”,  “monarch”,  and “DL”.  All formats, even those for en‐
        velopes, are in portrait orientation, with their  longer  dimen‐
        sion as the length.  Appending “l” (ell) to any of these denotes
        landscape orientation instead.  An output driver  typically  re‐
        quires command-line switches -p and -l to override the paper di‐
        mensions and orientation,  respectively,  defined  in  its  DESC
        file; see subsection “Paper sizes” of groff(1).

Some of the foregoing language is pretty recent.

By the way, papersize.tmac doesn't support formats A7, B7, C7, D7, but
the output drivers do--thanks to libdriver.  Does anyone know why this
is the case?
