Borderless printing Lightroom Epson XP-15000

Has anyone had success printing bordeless to an XP-15000 from Lightroom Classic on a Mac?  I have one of the supported paper sizes, have chosen a borderless printing preset (8 x 10 borderless) and still get a sizeable border on each print despite setting the all the margins at zero. I have tried to print scales to 120% to no effect.
