Transmit roll paper sensor status
□ When using serial interface, If set DTR/DSR control, the printer only transmits one
[Notes]
byte after the host have received the date (DSR signal is SPACE). If the host haven't ready to
receive data (DSR signal is MARK), the printer wait until the host have ready to.
If set XON/XOFF control, the printer only transmits one byte, and can not specify the DSR signal
status.
□ Execute this command when the data made in the print buffer area. So, between receiving this
command and transmitting status, may be one time spacing, it decides by the status of receive
buffer area.
□ When uses GS a to enable ASB, distinguish the transmitting status by GS r and ASB status by
appendix C.
□ Transmitting status type as follows:

Bit 2 and 3: When the roll paper end sensor detects no paper, the printer turns to offline, and don't execute this
command. So, bit 2 and 3 can not transmit no paper status.
