Downloading a font to a file

[dgm at agamik.co.uk (Douglas McCallum)]

We want to create EPSFs as part of our application. OSX has the 
facility to create EPSFs but they aren't comprehensive enough for high 
end artwork, as the colours aren't right, ie you can't differentiate 
between spot and process, and the EPSF header doesn't include the 
%%DocumentColors stuff.

So we create the EPSF ourselves, and there is one teeny problem how to 
download the font as part of the EPSF. NSFont allows you to create a 
postscript font from a screen font using printerFont, but there doesn't 
seem to be a method of getting the postscript out of the font and 
sticking it into a file.

After a lot of searching it seems to be a problem that no one has 
admitted to solving. Has anyone any udeas?

Thanks in advance
