Font in Gnuplot Postscript Terminal

I would like gnuplot to use the same font in the postscript-terminal as it does in the wxt-terminal. The Gnuplot help says that wxt uses "Sans" by default. Now, if i set the terminal to

gnuplot> set term post enhanced color "Sans" 12
Terminal type set to 'postscript'
Options are 'landscape enhanced defaultplex \
   leveldefault color colortext \
   dashed dashlength 1.0 linewidth 1.0 butt noclip \
   palfuncparam 2000,0.003 \
   "Sans" 12 '

then the font looks very different to the one in wxt. I am using Ubun开发者_JAVA技巧tu 10.04 lucid. Which font would you suggest me to use? Any ideas welcome. I've also tried "cm-super" to get latex-fonts (computer modern) in gnuplot. Actually it worked, but the text overlapped boxes and margins very often!

Since the considered plots are part of a LaTeX document, I decided to use the computer modern fonts described earlier.

gnuplot> set term post enhanced color fontfile "/usr/share/texmf/fonts/type1/public/cm-super/sfss1200.pfb" "SFSS1200"
Terminal type set to 'postscript'
Font file '/usr/share/texmf/fonts/type1/public/cm-super/sfss1200.pfb' contains the font 'SFSS1200'. Location:
   /usr/share/texmf/fonts/type1/public/cm-super/sfss1200.pfb
Options are 'landscape enhanced defaultplex \
   leveldefault color colortext \
   dashed dashlength 1.0 linewidth 1.0 butt noclip \
   palfuncparam 2000,0.003 \
   "SFSS1200" 14 fontfile "/usr/share/texmf/fonts/type1/public/cm-super/sfss1200.pfb" '

As already mentioned, you can install these under ubuntu by calling

# apt-get install cm-super

on the root command line.

Note that the characters in SFSS1200 describe font encoding (Latin1, ...), style (Sans-Serif, ...) and desired resolution in dpi.
