NOTES:

(1)The circles represent the IEEE1284 phases.

(2)This diagram can not be considered as the true state diagram.

(3)The host system can request the negotiation phase at any time, but the TK14 will only return a status byte if the host system has send the DEL EOT command previously.

(4)If the printer control of the host system does not have enabled or implemented the nibble mode according to the IEEE-1284 interface, only the compatibility mode will make communication possible. In this case, the error signaling is reduced to the information provided by the PError and nFault pins.
