• This command should not be used within the data sequence of another command that consists of 2 or more bytes. For example, If you attempt to transmit ESC 3 n to the printer, but DTR (DSR for the host computer) goes to MARK before n is transmitted and then DLE EOT 3 interrupts before n is received, the code H for DLE EOT 3 is processed as the code for ESC 3 H. • When Auto Status Back (ASB) is enabled using the GS a command, the status transmitted by the DLE EOT command and the ASB status must be differentiated. • If the n is out of the specified range, the printer ignores this command. n = 1: Printer status Bit Off/On Hex Decimal Function 0 Off 00 0 Not used.

Commands
•
This command should not be used within the data sequence of
another command that consists of 2 or more bytes. For example,
If you attempt to transmit
ESC 3
n
to the printer, but DTR (DSR
for the host computer) goes to MARK before
n
is transmitted
and then
DLE EOT 3
interrupts before
n
is received, the code
<10>H for
DLE EOT 3
is processed as the code for
ESC 3
<10>H.
•
When Auto Status Back (ASB) is enabled using the
GS a
command, the status transmitted by the
DLE EOT
command and
the ASB status must be differentiated.
•
If the
n
is out of the specified range, the printer ignores this
command.
n
= 1: Printer status
n
= 2: Off-line status
