Does anyone know how to turn on borderless printing for the 8740? A Google search seems to suggest there's an on/off setting somewhere, but I'm unable to locate it. The margin settings are greyed out in Windows which points back to the printer. I'm trying to print thank you cards and the design needs to at least come close to the edge of the page. As it is, the top has a .5" border and the bottom a .75" border. I've adjusted headers and driver preferences, even made my own borderless paper template, but still get the same top and bottom margins...
