Gnuplot scales down entire picture. I.e. if you do in gnuplot
plot sin(x)
set term post
set out "testpost.ps"
replot
set term post eps
set out "testeps.eps"
replot

The result will look the same if your postscript viewer scale
the picture to the same size (like, say, full-screen).
This is not the case if I do something like that in octave.
It appears to me the size of the picture gets enlarged w/o changing
size of the font. Then gnuplot scale down everything and
fonts become very small. The easiest fix -- do not use
"eps" option to gnuplot postscript terminal.

This is an interesting conclusion. I look at the postscript output
with either "evince", convert to pdf using "epstopdf" and use acroread
to look at the resulting pdf file, or just use ghostscript directly:
"gs -sDEVICE=x11 test_psc2.ps"

I look at the postscript file header using vi (vim to be more specific).

A4 paper as far as I remember is 210mmX297mm
72*210/25.4 = 595
72*297/25.4 = 842
(rounded to integer)

But I do not understand, why are you arguing with me. Are you NOT seeing these
problems?
