Note
To prepare the data to be printed with Borderless Printing,
create a document with the same size as the size of paper
you are printing on, and then paste the image so that it fills
the document area without leaving any margins. If you are
using an application that allows you to set margins, set the
left, right, top and bottom margins to 0 inches / mm. For
instructions on setting margins, refer to the instruction manual
of your application.
