Control Codes In The Text Mode - Epson MX-82 Operation Manual

(3) VT (Vertical Tabulation)
When the VT code is input, all data preceding this code is printed and the vertical
tabulation is made to a predetermined line position set by "ESC B" (up to 8 posi-
tions). If no vertical tab position is set by ESC B, the VT code behaves like the LF
code. Therefore, the paper is advanced one line after printing.
(4) FF (Form Feed)
The FF code causes the Printer to execute the printing of all data stored in the
print buffer and advances the paper to the next predetermined Top of Form posi-
tion.
NOTES: 1. The Top of Form is determined when the POWER switch is turned
on or the INIT signal is applied.
2. If the form length per page is not set, one page length of form is re-
garded as 66 lines with the DIP switch pin 1-2 on the control circuit
board set in the OFF position or 72 lines with the DIP switch pin
l-2 set in the ON position. (The amount of line spacing is governed
by the DIP switch setting at that time. When power is applied, the
amount of line spacing is set at 1/6 inch with the DIP switch 1-1
set in the OFF position or 1/8 inch with the DIP switch pin 1-1 set in
the ON position.)
3.2 Paper formatting codes
(1) HT (Horizontal Tabulation)
The HT code carries out the horizontal tabulation to a predetermined position
set by "ESC D" (up to 12 positions). The tab setting exceeding the column
length set by the DIP switch or ESC code will be ignored. In enlarged character
mode, the tab setting will not be effective and ignored.
(2) ESC D + nl + nz + + nk + NUL
This code specifies the horizontal tab stop positions. "n" denotes column posi-
tion where the print head stops. The first 12 tab stops per line are recognized
in the Printer, and subsequent tab stops are ignored. The tab stop positions can
be specified up to 96 columns in normal character mode and 159 columns in
condensed character mode. The excess tab positions, if specified, will be ig-
nored.
In enlarged character mode, the tabulation is not effective. To execute tabula-
tion, the HT code should be input.
The NUL code should be input as the command for the termination of the tab
set sequence, and the lack of this code will cause incorrect data printout.
