*1 • Definition of “receive buffer full”

•When the receive buffer capacity is specified to 4 KB (DIP SW1-2 is Off):

•If the DIP SW2-5 is off, 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.

•If the DIP SW2-5 is on, 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 138 bytes.

•When the receive buffer capacity is specified to 45 bytes (DIP SW1-2 is On):

•Regardless of the DIP SW2-5 setting, 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.

•The printer ignores the data received when the remaining space in the receive buffer is 0 bytes.

2.1.1.4 XON/XOFF transmit timing

When XON/XOFF control is selected, the printer transmits XON or XOFF signals as follows. Transmit timing differs depending on the DIP SW2-1 setting.
