Compatibility mode (data transmission from host to printer: Centronics-compatible)
The printer is not equipped with any online/offline switch. The printer is placed into offline
status in any of the following conditions:
1. When the power is turned on or until the printer becomes ready for data transmission after it
is initialized by the reset signal (nInit) from the interface.
2. During the self-test.
3. When the cover is open.
4. During paper feeding using the
FEED
button.
5. When the printer stops printing due to a paper-end (only when the paper roll is not present).
6. During macro executing standby status.
Outline Compatibility mode supports the compatibility with
Centronics parallel interface.
