Precautions

(1) The Negotiation phase is triggered when the IEEE 1284 Active signal sent by the host becomes High.

(2) In Compatibility mode, the time when the negotiation process begins is, as a general rule, after the host

sets nStrobe to High and then the printer outputs an nAck pulse.

Once the nStrobe signal is set to High, however, the printer immediately moves into the Negotiation

phase when the high state of IEEE 1284 Active is detected, even if the nAck pulse has yet to be output or

is being output. In this case, if the printer has returned to Compatibility mode after Termination, no nAck

pulse will be output.

(3) Negotiations can be entered from the Busy or Error state of the Compatibility mode. In this case, the

printer will not return to the Busy or Error state before the negotiations, but still remains in the printer

state just after Termination.

(4) If the host requested a communication mode that is not supported by the printer, it must move into the

Termination phase and return to the Compatibility mode.
