I don't think this is true.  Could you give a specific example?
For instance, the postscript driver itself knows little about text
layout.  That information is not available until much later, when
the output file is run through a postscript interpreter 
(e.g. a PostScript printer, ghostscript). By then it is far to late
to feed any information back to the gnuplot core routines.

I'm still not sure what information you mean.
Are you talking about the estimated string length?
That estimation is actually done by a special driver that
does nothing else - estimate.trm.
