4) XON/XOFF timing
When XON/XOFF control is selected, the TM-U295 transmits XON/XOFF signals as follows:
[XON transmission]
À
When the printer first becomes ready to receive data after turning on the power.
Á
When the receive buffer is released from the buffer full state.
Â
When the printer switches from off-line to on-line.
[XOFF transmission]
Ã
When the receive buffer becomes full.
Ä
When the printer switches from on-line to off-line.
NOTE: The XON code is 17 (11H) and the XOFF code is 19 (13H).
5) Notes on resetting the printer using the interface
The printer can be reset through the interface (pin 6 or 25) by changing the DIP switch settings
accordingly (see Table 2.1.2).
