FF
Vertical tab stops are referenced in print
lines from
the top of
form which is print
line
one
.
The
distance from the top of form is
based on the currently active line spacing and the line number of
the vertical
tab stop.
The
last valid tab stop for a given page is
the one which is less than
the
currently active bottom margin
or
page
length.
If
the last tab stop is less than or equal to
the
current
line
position
,
then the vertical
tab
command acts
as
a line
feed
command.
If
no vertical tab stops are
set,
the paper is
,,._
advanced one line
space.
Vertical tab stops are set
by
using
the
ESC B command. Vertical tab stops are reset when the printer is
turned on or when an
ESC R
command
is processed
.

trailing edge of
the
paper.

paper
is
advanced a distance equal to the page length and
the
trailing edge of the paper is
not
sensed.
For cut sheet applica-
tions, the page
is
ejected
but
the

is
not
fed
or
requested
until the printer
is
ready
to print the next
line.
