The FM to R is DEC AA-JP25B-TK, "PostScript Translators Reference Manual"
At least that's the version I have.

It's not one of DEC's best, IMHO, but is a little better than guesswork.
The translator seems to (?) run in the host computer.  It converts the
"other" formats into PostScript.  It should take about the same escape
sequences as a normal DECwriter -- except sometimes you don't get the same
results.  For example, on an LA120, etc. changeing the horizontal pitch to
16.5 automatically gives you a smaller font.  On the Printserver it doesn't.

Here's my guess at decoding...

<ESC>[27 J   -- PFS page format select (undocumented, should it be "?27"?)
<ESC>[4w     -- DECSHORP set horizontal pitch to 16.5 cpi
<ESC>[15m    -- SGR select graphic rendition (use Courier 6.7 point font)
<ESC>[?7l    -- DECAWM set mode auto wrap off
<ESC>[1;270s -- DECSLRM set left margin to 1, right to 270

arguments for PFS:
I will give the even numbers for portrait orientation, add 1 for landscape.
"Normal" gives an ANSI standard 1/2 inch left and top margin and 5/6 bottom.
"Ext" or Extended gives a minimum top and bottom margin.
"private" adds a minimum left margin.
0   (same as ?20) default.
2   normal A4
4   normal North American letter
6   Extended A4
8   Extended legal
?20 Ext North American private
?22 Ext A4 private
?24 Ext legal private
?26 Ext B private

For fudging character sizes, the GSM and GSS sequences look interesting.
(I haven't tried them, mind.)

GSM (Graphic Size Modification) sets the height and width:
    <esc>[Pn1;Pn2 B        -- the space IS significant
          Pn1 is a decimal number for percent of GSS height
          Pn2 is a decimal number for percent of GSS width

    so it seems that <esc>[200;50 B  will give a character twice as high and
half as wide as the GSS setting.

GSS (Graphic Size Selection) sets the height. (width is implicit)
    <esc>[Pn C             -- the space is part of the syntax
          Pn is a decimal number for percent of "font height set by SSU
             sequence" (whatever that is.)

Good luck.
