Printing Issues

Hello, 

I'm trying to print 11x17 documents and they always come out blown up and gray. I've seen an issue on the support page similar to this where it only prints the top left of the image. The FAQ is specific to HP printing and I'm using a Xerox.  In my case, it is only printing the top left but enlarging it quite a bit as well.

I've deleted the printer and all of the driver files and re-added it. I've even tried multiple drivers ( a printer specific driver and a global type print driver). When I do this, it works for a few days, but then reverts back to blowing it up. I have no other issues in any other applications.  Perhaps I should note as well that the print preview screen looks correct.

In addition to this, it recently started printing gray rather than black. Any thoughts?

Thanks in advance!
