Left and Right Margins
n1, n2 = 1 - 255
Parameter n1 indicates the number of the column, in the current print pitch, for the left
margin.
Parameter n2 indicates the number of the column, in the current print pitch, for the right
margin.
Value n2 - n1 must be more than 1. Values that go beyond the right edge of the paper are
set back to the right margin.
When parameters n1 and/or n2 are set to 0, they indicate that the current margins remain
valid.
The margins are set according to the current print pitch, but their absolute position does
not change, even if the pitch is then changed.
