I think you may need to also use the "fonts" pAramater to postscript().
See in '?postscript':

  fonts: a character vector specifying additional R graphics font
        family names for font families whose declarations will be
        included in the PostScript file and are available for use
        with the device. See 'Families' below.  Defaults to 'NULL'.

Since the Computer Modern family is most probably not built in
to your printer, the PostScript file will need to include font
definitions for these fonts. If I understand aright, this is what
would be achieved by appropriate use of the "fonts" parameter.

If the font definitions are not included, the calls for them will
not be recognised by the printer which may then substitute a default
(likely to be Courier).

See also the section "TeX fonts" in '?postscript'.
