NOTES:
1. When the DIP switch 1-2 is Off (the receive buffer capacity is specified to 45 bytes):
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.
2. When the DIP switch 1-2 is On (the receive buffer capacity is specified to 4 K bytes):
When the remaining space in the receive 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.
3. The printer ignores the data received when the remaining space in the receive buffer is 0 bytes.
Off-line
2. During the self-test. BUSY BUSY
3. When the cover is open.

BUSY
4. During paper feeding using the paper FEED
switch.
—BUSY
5. When the printer stops printing due to a
paper-end (only when the paper roll is not
present).
—BUSY
6. During macro executing standby states. — BUSY
7. When an error has occurred. — BUSY
8. When the receive buffer becomes full. (*1) BUSY BUSY
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 self-test.
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.
