It depends how you wire the ports together. An IRQ is generated at the
host by nAck (and, with some chipsets in some modes, nFault). So if you
have nDataStb/nAddrStb wired up to nAck, yes it will generate an IRQ on
the receiving end.
EPP also has an 'interrupt' cycle, which is presumably supposed to
generate an interrupt on the receive end as well, although I forget which
pin that involves.
