Use this sequence to establish the form length of the page. The max-
imum form length is determined by page orientation, origin point, and
paper size. The form length established by this sequence may be
expressed in either pixels, decipoints, or character cells (lines)
depending on the PUM and SSU sequences.
The DECSLPP sets top margin to 1 and bottom margin to the speci-
fied form length.

This sequence sets the top and bottom margins relative to the current
origin point. The top margin is the page home position. The bottom
margin is the page end position. The printer cannot print text on the
current page outside these margins. (It can, however, draw vectors
outside the margins.)

The new margins take effect as soon as they are received by the
printer with the following exceptions:
If the value of
Pn
1
is omitted or set to 0, the top margin does not
change.
Pn
A numeric value greater than 0 and less than or equal
to the maximum value for the current paper size. If
Pn
is 0, DECSLPP sets form length to the maximum
value for the paper size. If
Pn
is greater than the
maximum value for the paper, DECSLPP sets form
length to the maximum value.
Pn
1
Numeric value for top margin expressed in unit of
measure determined by PUM and SSU.
Pn
2
Numeric value for bottom margin expressed in unit of
measure determined by PUM and SSU.
