3)
ESC
2 (Escape 2)
Receipt of an
"ESC"
followed by ASCII code
"2"
causes the line spacing to be set at 1/6 inch.
When the
POWER
switch
is
turned on, the line
spacing
is
set at initia11/6 inch. The
ESC
2 code
is
also a command to execute
"ESC
A+n"
modes
(described later).
4)
ESC
8 (Escape 8)
The
ESC
8 code makes it possible to transmit data
even if there
is
no paper in the Printer. This code
should be transmitted before the Printer runs out
of paper. After transmitting this code, when the
Printer runs out of paper, the
PE
signal of the
interface connector turns to High level; the
ERROR
signal remains at High level.
5)
ESC
9 (Escape 9)
This code cancels the
ESC
8 condition. When the
power
is
turned on, the Printer
is
initialized into
ESC
9 status. Therefore, the Printer cannot
receive data when there
is
no paper.
6)
ESC
SI
This code functions the same
as
"SI".
7)
ESC
SO
This code functions the same
as
"SO".
(b)
ESC
alphabetic control
Receipt
of
an
"ESC"
code followed by ASCII code
"X"(alphabetic code) permits each of the following
functions to be performed.
Note:
"n"
represents a 7-bit binary number, and the
most significant bit is not treated as data.
"+"
is
inserted for the purpose
of
legibility only, and
should not be input in actual operation.
1)
ESC
A+n
This code specifies the amount
of
line spacing in
the Line Feed 1
«n>
10<85
(Decimal):
"n"
is
a
binary number.
"n"=
1
is
equivalent to 1/72 inch
paper advancement. Since the distance between
any two dot wires
of
the print head is 1/72 inch,
any line spacing in increments proportional to the
distance between the dot wires can be established.
