NOTE: For current loop operation, a data transfer rate greater than 1200bps cannot be guaranteed.
Handshaking Timing
When the amount of buffer space for input data becomes 256 bytes, the printer indicates that it is “not
ready
to receive data” by outputting the X-OFF code and/or REV signal (polarity can be selected by
jumper setting). When the available buffer space becomes 528 bytes, the printer indicates that it is
“ready to receive data” by outputting the X-ON code and/or changing the REV signal.
Error Handling
An asterisk (*) is printed when a parity error is detected. Other errors (e.g., “overrun error” and “framing
error”) are ignored.
