10	CS1	Input	This signal indicates whether the host computer is BUSY or READY.
11	CS2		CS1>CS2 indicates that the printer is READY and CS1<CS2
			indicates that the printer is BUSY.
			1) When DTR>DSR is selected:
			The signal is checked and data is transmitted only when the host is
			ready to receive data (READY) (except for transmitted by DLE EOT
			or GS a).

			Transmits data regardless of the status of this signal.

*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.
