XON/XOFF
When XON/XOFF control is selected, the printer transmits the XON or XOFF signals as follows. The
transmission timing of XON/XOFF differs, depending on the setting of DIP switch 2-1.
20 DTR Output 1) When DTR/DSR control is selected, this signal indicates
whether the printer is BUSY.
SPACE status
Indicates that the printer is ready to receive data.
MARK status
Indicates that the printer is BUSY. Set BUSY conditions with
DIP switch 2-1.
2) When XON/XOFF control is selected, the signal indicates
that the printer is properly connected and ready to receive
data from the host. The signal is always SPACE, except in the
following cases:
During the period from when power is turned on to when
the printer is ready to receive data.
During the self-test.
25 INT Input Changing DIP switch 2-8 enables this signal to be used as a
reset signal for the printer. The printer is reset if the signal
remains at SPACE for a pulse width of 1 ms or more.
