This signal indicates whether the host computer can receive data.
(H/W flow control)
1) MARK(Logic1) : The host can receive a data.
2) SPACE(Logic0) : The host can not receive a data.
3) The printer transmits a data to the host, after confirming
this signal.
4) When XON/XOFF flow control is selected, the printer does
not check this signal.

This signal indicates whether the printer is busy. (H/W flow control)
1) MARK(Logic1) : The printer is busy.
2) SPACE(Logic0) : The printer is not busy.
3) The host transmits a data to the printer, after confirming
this signal.
4) When XON/XOFF flow control is selected, the host does
not check this signal.
Table 3-15 RS-232C Pin Description
3-5-1(e) H/W Flow Control
When DTR/DSR flow control is select, before transmitting a data, the Printer checks whether the host is
BUSY or not. If the host is BUSY, the Printer does not transmit a data to the host. If the host is not BUSY, the
Printer transmits a data to the Host. The host is the same. Refer to the Interface Part of Chapter 4-3 Special
Circuit Diagrams.
