* This connection at the host side of the interface would depend upon the pin that is being used as the Ready/Busy signal by
the driving software. Typically, on a PC, it would be either CTS (pin5) or DSR (pin 6) on a DB-25 connector.
Communicates with the host to determine if the printer is ready to receive data by sending "XON" (HEX 11H) or "XOFF" (HEX
13H) code to the TD line. The single and multiple item buffers are switchable in the Interface Mode of the printer.

NOTE: Depending on the host used, it may be required to loop CS and RS
(maintaining at high-level) on the host side. For more information, refer to the host
computer documentation.
