valid.
Top margins greater
than the
page length
result in both the
top and
bottom margins being
set inactive.
The
bottom margin parameter
(bm)
is a two-byte parameter which
specifies
the distance from the
top of
form to
the top edge of the
bottom margin zone in
inches.
The distance
is
equal to 256 times
Hbm
plus
Lbm
divided
by 1440
inches. A
bottom
margin greater
than the top margin and less than
or
equal to the page length
is
considered to
be
valid.
A bottom
margin
less
than
or
equal to the
top
margin
or
greater
than
the
page
length
results in both the top
and bottom
margins
being set
inactive.
For example, to set a top and bottom
margin
of 1
inch,
assuming
an 11-inch page, the top margin would
be
set to
tm
=
1 inch and
the bottom margin would be set
to
bm
=
10 inches. The top
margin
parameter
values would
be
Htm
=
5 and
Ltm
=
160.
The
bottom margin parameter values
would
be
Hbm
=
56 and
Um
=
64.

This command is used to identify the code page id of the font. The
code
page id of the embedded font is
437.
This is
the
standard
IBM Personal Computer
US
code
page.
The code page id number
is
a method of identifying to the printer the character-to-code-
point assignment allowing the printer to support different
lan-
guage requirements.
The
parameter values of
Ln
and
Hn
specify the number of param-
eter bytes which follow. The number of parameter bytes is
256
times
Hn
plus
Ln.
The first two parameters following the
Hn
parameter are not used
by the
printer.
It is recommended that zero be used for each of
these
parameters.
These
parameters must be included.
