3. Serial interface
(a)
Receive data
Either DTR/DSR or XON/XOFF control is selectable. Changes in
DTR signal and XON/XOFF transmission are as follows:
[DTR MARK]
* The period from when the power is turned
on to when the printer is first ready to
receive data.
* In an error state.
* When the remanig space in the recive
buffer becomes 10 bytes.
[DTR SPACE]
[XON Transmission]
[XOFF Transmission]
* When the printer is first ready to receive
data after power-on.
* When the remaining space in the receive
buffer becomes 20 bytes.
* When the printer first becomes ready to
receive data after turning the power-on.
* When the remaining space in the receive
buffer becomes 20 bytes.
* In an error state.
* When the remaining space in the receive
buffer becomes 10 bytes.
(b) Transmit data (Status information transmission)
When DTR/DSR control is selected, data is transmitted after confirming
that DSR is SPACE. When DTR/DSR control isn’t selected, data is
transmitted regardless of the DSR state.
