2) ESC 1 (Escape 1)
Receipt of an "ESC" followed by ASCII code "1" causes the line
spacing to be set at 7/72 inch. Input of the ESC 2 code or INIT sig-
nal to the interface connector or turning the power off and on
again causes the line spacing to return to l/6 inch.
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 initial 1/6 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.
