That work flow is rather circumventional.  That could be a sizeable part 
of the problem.  The conversion to PDF and the PDF interpreter introduce 
additional variables that gnuplot has no control over at all.  You may 
want to check against direct output of gnuplot-generated PS to the 
plotter/printer.

PostScript is a vector-based file format --- you shouldn't really have 
to make a bigger image to get more resolution.  Just tell the printer
or some other intermediate processing tool to blow up the thing by 
whatever factor you need.

'set xtics' can almost certainly help you with that.

You're using all the way that there is, already.  Setting 'origin', too, 
may help to move the plot to a better position, though ;-)
