K represents 1024 bytes. N/A means non-applicable. Note: When using serial communication, the printer signals the host computer to stop transmitting bytes when the serial input buffer is within 640 bytes. In addition, when XON/XOFF protocol is used, the printer signals the host computer to stop transmitting when the serial input buffer is 384, 256, and 128 bytes from full.
