Sorry, I don't know exactly. The formats that can be called up in the driver can be printed borderless. I mainly print 10x15, 13x18, A4, A3. They all go borderless

If you have paper in this format, I see no reason why it shouldn't print with a margin. You can freely select the paper size and the print margin under "user-defined", whereby print margin = 0 = margin waste is technically possible. However, I would recommend printing with a small white margin and a 2 mm bleed and then cutting the paper to the correct format. Of course, you will need a good cutting machine for this. The reason: printing with a bleed makes a bit of a mess in the printer, because some ink must inevitably be left behind if it is to print over the edge. With this ink residue in the printer, you can quickly smudge a clean sheet.
Good luck and good luck, LG, Sam
