The printer does not have an on-line/off-line switch.

The printer goes off-line:

• Between when the power is turned on (including reset using the

interface) and when the printer is ready to receive data.

• During the self-test.

•When the cover is open.

• During paper feeding using the paper feed button.

• When the printer stops printing due to a paper-end (in cases when

an empty paper supply is detected by either paper roll end detector

or the paper roll near-end detector with a printing halt feature by

ESC c4).

• During macro executing stand by status.

• When a temporary abnormality occurs in the power supply voltage.

• When an error has occurred.
