Bought a iP8720 to print 12x12 borderless. So far, no luck. Help.

I bought the iP8720 large format printer specifically to print borderless on 12 x 12 paper.  Seems impossible.  Anybody know any tricks?  Thanks for any help.

Anyone ever figure this out. I bought the same printer for the same 12x12 printing purposes and I am stumped!

I also bought for the same reason, they advertise it as printing 12x12! Really frustrating
