Print warnings

[Richard Campbell]

I have gnuplot (compiled from source) and a 64-bit build of Octave 3.4.0 on OSX 
10.6.6, using Jarno's blaswrap.c. GNU sed and flex compiled from source with 
--prefix=/usr/. No ghostscript, and running configure with --disable-docs.

A temp.eps file is successfully produced - the font appears to be some form of 
Courier. When I run the same code on the same machine in the old Octave 3.2.3 
.app bundle, it looks more like Helvetica.

Any ideas as to what is causing these warnings, and how to make them go away? 
As Ben mentioned, ghostscript is required to print to formats other than .eps, 
but I'm getting warnings even when I print to .eps.
