2.3.2- Change between online and offline mode

The printer is in offline mode:
1) When powering up or resetting the printer, until the printer is ready to receive data.
2) When performing the self-test.
3) When the cover is open.
4) After pressing the Paper feed button (FEED) while the paper advances.
5) When 'out of paper' causes the printer to stop printing.
6) During macro execution in standby mode.
7) When the power supply has a temporal abnormal voltage change.
8) When an error has occurred.

2.3.3- Assignments of RS-232 connector terminals

The assignments of the terminals of the RS-232 connector and the functions of its signals are described
in the following table:

Data reception
Same as DTR signal
This signal indicates whether the host system is ready to
receive data.
When the XON/ XOFF control is selected, the printer does
not check this signal.
