Printing edge-to-edge

[konicaman]

I have a problem printing edge-to-edge on my Epson Stylus Pro 3880 from XnView. If I set the margins to 0, I still get white borders (app. 3 millimeters) around the whole frame no matter what size I am printing in. The printer certainly is capable of doing edge-to-edge. I am sorry if this has been asked before, but I could not find anything when searching. Any help would be appreciated
