1 = Transmit printer status
2 = Transmit RS-232C busy status
3 = Transmit error status
4 = Transmit receipt paper status
5 = Transmit slip paper status
The command is ignored if n is out of range.
Note:
An application using the DLE sequence must send EOT within 100
milliseconds of DLE or the printer will misinterpret the DLE and execute a
Clear Printer command. Avoid this possibility by using the GS EOT n
sequence which is handled exactly the same as DLE EOT n.
