windows 7 machine cutting off borders when printing to kyocera copier

We have a new machine running windows 7 and MS 08.11.07.443 that we we plot to our Kyocera copier it cuts off the bottom and right side of our 11x17 prints.  It plots to our HP plotter just fine and all other machines plot the same file just fine.  Is there something in the windows driver that could be telling MS that it can print edge to edge when it can't?  I know the drivers from one OS to the other are different so I thinking that it has something to do with that but I'm not sure what to do about it.  This is why I liked bentley drivers and not windows ones.
