NOTES: • Set the handshaking so that the transmit data can be received.

Transmit data to the printer after turning on the power and initializing the printer.

2.1.1.6Notes on setting DIP switch 2-1 to ON

1)The printer mechanism stops but does not become busy when: an error has occurred, the cover is open, printing stops due to a paper-end, or paper is fed using the paper feed button.

2)When setting DIP switch 2-1 to ON to enable handshaking with the printer, be sure to check the printer status using the GS a command and the ASB function. In this setting, the default value of n for GS a is 2. The printer automatically transmits the printer status, depending on online/offline changes.

3)When using DLE EOT, DLE ENQ, and DLE DC4 be sure that the receive buffer does not become full.

When using a host that cannot transmit data when the printer is busy:

If an error has occurred, DLE EOT, DLE ENQ, and DLE DC4 cannot be used when the printer is busy due to a receive buffer-full state.

When using a host that can transmit data when the printer is busy:

When the receive buffer becomes full while transmitting bit-image data, DLE EOT, DLE ENQ or DLE DC4 used while sending the bit-image data is processed as bit-image data. The data transmitted when the receive buffer is full may be lost.

Example: Check the printer status using GS r after transmitting each line of data and use the 4 KB receive buffer. Transmit one line of data so that the receive buffer does not become full.
