What does Borderless printing mean?

Borderless printing meaning in Computer Science Dictionary

instead named full-bleed printing, borderless printing is a printing strategy which makes a printer print a picture without having any margin or other border. This type of publishing is particularly useful when you're printing a photo but try not to desire a border, printing a graphic that needs multiple sheets of paper for one picture (e.g. billboard or larger photo), or printing a template that really needs a page.
