ESC v
[Name] Transmit paper sensor status
[Format] ASCII ESC v
Hex 1B 76
Decimal 27 118
[Description] Transmits the status of paper sensor( s) as 1 byte of data
[Notes]
• GS r 1 can also be used to check the status. GS r is recommended for
transmitting the paper sensor status. ESC v is not a recommended
command.
• When DTR/DSR control is selected by DIP switch (Handshaking) with a
serial interface, the printer transmits the status after confirming that the
host is ready to receive data. If the host computer is not ready to receive
data, the printer waits until the host becomes ready.
• When XON/XOFF control is selected by DIP switch (Handshaking) with a
serial interface, the printer transmits the status without confirming whether
the host computer can receive data.
• The peripheral device status to be transmitted is as follows:
