[Notes] • The status is transmitted whenever the data sequence <10>H<04>H<n> (1 ≤ n ≤ 4) is
received. For example,
In
ESC
∗
∗∗
∗ m n
L nH [d] nL+256nH, d1=<10>H, d2=<04>H, d3=<01>H
• 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.
