Have you checked your Page Tiling? (View>Show Page Tiling) The border that you see will show you how it prints. But you can save your file as an Illustrator PDF and then open it with Adobe Reader and given that your printer is borderless . . . you can print to the edges. But a bleed is something where your design extends beyond the edge of the finished product and you cut into the bleed, trimming off some of the art and leaving a smaller product than the original paper size.
