| 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 | |
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. |
*1 • Definition of “receive buffer full”
•When the receive buffer capacity is specified to 4 KB (DIP
•If the DIP
•If the DIP
•When the receive buffer capacity is specified to 45 bytes (DIP
•Regardless of the DIP
•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
Table 2.1.2 XON/XOFF Transmit Timing
| Printer status | DIP SW | |
| ON | OFF | |
|
| ||
XON | ① When the printer goes online after turning on the power (or | Transmit | Transmit |
transmission | reset using interface) | Transmit | Transmit |
| ② When the receive buffer is released from the buffer full state | ||
| ③ When the printer switches from offline to online | — | Transmit |
| ④ When the printer recovers from an error using the | — | Transmit |
| DLE ENQ 1 or DLE ENQ 2 commands |
| Transmit |
XOFF | ⑤ When the receive buffer becomes full | Transmit | |
Transmission | ⑥ When the printer switches from online to offline | — | 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.
