Printing problem

[David Squance]

I didn't get a response on this earlier, but I'm wondering if anyone 
knows if setting printrotated to true can mess up the printer default 
settings in some way.  I'm going to be in deep kaka at work, if I can't 
get this fixed.  I tested an app on a couple of PCs at work, not having 
a windows machine at home, and now we can't seem to get them back to 
having portrait as default.  Is there some simple solution?
Thanks,
Dave
