-
The status is transmitted whenever the data sequence for DLE EOT BS n (n = 1) is
received.
Example:
In ESC * m nL nH[d] nL+256xnH, d1 = (10)H, d2 = (04)H, d3 = (08)H, d4 = (01)H.
-
This command should not be contained within another command that consists of two or
more bytes.
Example:
If you attempt to transmit ESC 3 n to the printer, and then DLE EOT BS 1 interrupts
before n is received, the code (10)H for DLE EOT BS 1 is processed as the code for ESC
3 (10)H.
-
This command is unavailable when using the ESC = n (Select Peripheral Device) to
select the printer to be disabled.
-
This command is ignored while the printer transmits reading results of MICR (FS a 0 n,
FS b).
-
When Auto Status Back (ASB) is enabled using the GS a command, the
status transmitted by the DLE EOT BS command and the ASB status must
be differentiated.
-
If the value of n is out of the specified range, the printer ignores this
command.

personal check or cleaning sheet, respectively.
