I Print with Upper Left of Sheet as Starting Point (See p. 4-58)
Since printing is usually performed with the upper-left 5 mm (10 mm for envelopes)
margin within the printable area of a sheet as the starting point, a certain portion (lower
right) may be missing when printing data with no margin. In this case, you can print with
the upper-left 0 mm margin as the starting point, and as a result, all sides of the sheet will
be printed evenly.
