Serial Matrix Vertical Formatting
In
Serial Matrix protocol, vertical formatting is always enabled. F
orms
control is accomplished
by
a set of programmed vertical tabs. V
arious lines of
the form are assigned vertical tabs which
are
then accessed by control code for rapid paper advancement to the tab position. T
wo codes
are
used for controlling vertical
tabs: ESC B for single channel tab setting, and VT to execute a
vertical
tab. These codes and their parameters are described in the P
rogramming chapter. The
VFU Loaded indicator on the control panel will not light when vertical tabs are loaded for
forms
control.
Executing Vertical Tabs
The
vertical tab execute code is VT
. When sent, it prints the
contents of the print buffer (if data
is in the buffer) and causes paper movement to the next predefined vertical tab position. If a
tab position is not defined, the paper is moved to the next line at the current line spacing. If a
tab
position is at the current line, the paper is moved to the next tab position. If no tab positions
are defined between the current line and the end of the form, the paper moves to the next top-
of-form
(TOF).
