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.

XON/XOFF transmission timing

See “XON/XOFF transmission timing” under the “RS-232 Serial Interface” section earlier in this

chapter.

For the DIP switch settings for the offline status, see Chapter 1.

2) When XON/XOFF control is selected,

this 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 DR1>DR2 (READY) to

indicate that the printer is ready to receive data, 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.

10 CS1 Input 1) When DTR/DSR is selected, this signal indicates whether the host computer is

BUSY or READY. CS1>CS2 indicates that the printer is READY and CS1<CS2

indicates that the printer is BUSY.

11 CS2 The signal is checked and data is transmitted only when the host is ready to

receive data (READY) (except for transmissions by
