Pin number Signal name Signal direction Function
2) When XON/XOFF control is selected:
The signal indicates whether the printer is correctly
connected and is ready to receive data. SPACE
indicates that the printer is ready to receive data. The
signal is always SPACE except in the following cases:
· During the period from when the power is turned on
to when the printer is ready to receive data
· During the self-test
25 INIT Input Changing the DIP switch setting enables this signal to be
used as a reset signal for the printer.
The printer is reset when the signal remains SPACE for
1 ms or more.
NOTES:
1. When the remaining space in the receive buffer drops to 16 bytes, the printer status
becomes "buffer full" and it remains "buffer full" until the space in the receive buffer
increases to 26 bytes.
2. The printer ignores the data received when the remaining space in the receive buffer
is 0 bytes.
2.1.1.4 XON/XOFF transmit timing
When XON/XOFF control is selected, the printer transmits XON or XOFF signals as follows.
Transmit timing differs depending on the DIP SW1-3 setting.
Table 2.1.2 XON/XOFF Transmit Timing
DIP SW 1-3 status
Printer status ON OFF
XON transmission
① When the printer goes on-line after turning on the
power (or reset using interface)
Transmit Transmit
② When the receive buffer is released from the buffer
full state
Transmit Transmit
③ When the printer switches from off-line to on-line
— Transmit
④ When the printer recovers from an error using the
DLE ENQ 1
or
DLE ENQ 2
commands
— Transmit
XOFF Transmission
⑤ When the receive buffer becomes full
Transmit Transmit
⑥ When the printer switches from on-line to off-line
— Transmit
NOTES:
· The XON code is <11>H and the XOFF code is <13>H.
· In case ③, XON is not transmitted when the receive buffer is full.
· In case ⑥, XOFF is not transmitted when the receive buffer is full.
