Hello,
There was a fix introduced some time ago to the PostScript driver to honour the xsize and ysize settings via spage():
http://plplot.svn.sourceforge.net/viewvc/plplot/trunk/include/ps.h?r1=6457&r2=9034
It would be great to have an analogous functionality for the xoffset and yoffset settings.
As of now both are hardcoded in ps.h

Fixed in svn.
