This signal indicates whether the host computer

SPACE indicates that the host computer can
receive data, and MARK indicates that the host
computer cannot receive data.
When DTR/DSR control is selected, the printer
transmits data after confirming this signal (except
when transmitting data by DLE EOT, and GS a).
When XON/XOFF control is selected, the printer
does not check this signal.
