2.1.3.2 Switching between online and offline
The printer does not have an online/offline switch.
The printer goes offline:
1) Between when the power is turned on (including reset using the interface) and when the printer is
ready to receive data.
2) During the self-test.
3) When the cover is open.
4) During paper feeding using the paper feed button.
5) When the printer stops printing due to paper-end (in cases when an empty paper supply is
detected by either paper roll and detector or the paper roll near-end detector with a printing halt
feature set enabled due to paper shortage by ESC c 4).
6) During macro executing standby status.
7) When a temporary abnormality occurs in the power supply voltage.
8) When an error has occurred.
9) When the receive buffer becomes f ull. (*1)
*1 • Definition of “receive buffer full”
• When the receive buffer capacity is specified to 4 KB (DIP SW1-2 is Off):
• If the DIP SW2- 5 is off, when the rem aining space in the rec eive buffer drops to 128 bytes,
the printer status becomes “buffer full” and it remains “buffer full” until the space in the
receive buffer increases to 256 bytes.
• If the DIP SW2- 5 is on, when the remaining spac e in the receive buff er drops to 128 bytes,
the printer status becomes “buffer full” and it remains “buffer full” until the space in the
receive buffer increases to 138 bytes.
• When the receive buffer capacity is specified to 45 bytes (DIP SW1-2 is On):
• Regardless of the DIP SW 2-5 setting, 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.
• The printer ignores the data received when the rema ining space in the receive buffer
is 0 bytes.
* For notes on setting DIP switch 2-1 to ON, refer to Section 2.1.1.6.
