[Notes]
Real-time transmit the printer status specified by parameter n:
n = 1: Transmit printer status
n = 2: Transmit off-line status
n = 3: Transmit error status
n = 4: Transmit paper sensor status
• When the printer receives the command, it returns relative status immediately.
• Please avoid inserting this command between 2 or more bytes command.
For example:
In the process of sending
ESC 3 n
to printer, hardware device already sets flag for
DLE EOT 3
before printer receiving n, then the printer take
<10>H
of
DLE EOT 3
as
parameter of
ESC 3 n,
which is equivalent to send
ESC 3 <10>H
.
• The printer transmits the current status. Each status is represented by one-byte data.
• The printer transmits the status without confirming whether the host computer can
receive data or not.
• The printer executes this command immediately upon receiving it.
• This command is effective to printers with serial port and USB port. Printer will
execute this command immediately in any status, including printer off-line status,
buffer area full status and error status.
