Three-sided Borderless Printing on Roll Paper
In normal borderless printing, paper sizes that match the width of the roll paper are combined to print without
borders on all four sides.
If you use the three-sided borderless printing feature, you can combine paper sizes that don't match the roll
paper width, and print with no borders on three sides. However, if you perform three-sided borderless
printing, you need to cut the right side of the paper after printing.
