To guard against this situation, an application should determine the cause of a
busy condition and take appropriate action or pace further real time commands
to avoid filling the buffer. There are a minimum of 256 bytes available in the
printer’s buffer when it goes busy.
The commands are listed numerically by hexadecimal code.
Real Time Status Transmission
Transmits the printer status in real time. In RS-232C communications, the
printer transmits only one status byte before checking the DSR state. The
command is ignored if
n
is out of the specified range. Slip status may be
incorrect for paper with holes.

The printer performs this command even when it is offline, receive buffer is full,
or in an error state. Do not use this command within the data sequence of
another command that consists of two or more bytes. The Real Time Status
Transmission command is transmitted any time the command sequence 10 04 (
n
= 1-6) is received, even if the sequence is part of another command.
