QTR-Quadtone RIP

HELLO ALL,

I believe I may have posted this question at some point in the past, but not sure. I'm using a 7600 and have various custom paper sizes set up for borderless printing. Of course they all work fine with the Epson borderless(No Margins) driver, but thus far I have not been able to find a way to have QTR print borderless.  If anyone has managed a work around for this issue could you please post a reply to that effect. I use Mac, Tiger 10.4.11.  

Thank you.
Gary
