#1 is intended. The current sources respect the figure properties,  
papersize, papertype, paperpostion properties, etc.

	figure (1)
	clf
	plot (randn (50, 1))
	set (gcf, "paperunits", "inches"); # the default is "inches"
	paper_size = [8.5, 11.0];
	set (gcf, "papersize", paper_size)
	set (gcf, "papertype", "usletter")
	set (gcf, "paperposition", [0.5, 0.5, paper_size-1.0])
	print (gcf, strcat ("figtest.ps"), "-dpsc")

While listeners still need to be included to simplify specifying these  
properties.

Regarding #2, gnuplot position's the tick-labels, axis-labels, and  
title in a more liberal manner than does Matlab. However, the subplot  
does position the axes in a compatible manner. This results in problem  
with your titles. This problem is also improved by setting the  
paperposition property so that the figure fills the full page.
