Use USB, Firewire or maybe Ethernet.
Infinity, I should think.
while (1) ;
Can produce an infinite delay in any applictions.
Higher than what?
This makes no sense, as Grant has pointed out. Do you mean *minimum* delay? Are you trying to figure out maximum data rate for a parallel port? If so, it depends on a few things, like how it's strobed. If you're outputting data using the normal printer port strobe system, a max of around 1Mbyte/sec is ballpark - but this depends on a lot of other things.
I think you need to rephrase your question, and provide a bit more detail as to what you're trying to do.

Ok.First I appologize for my bad usage of language. Yes it is minimum delay and maximum transfer rate can be handled.
I want to monitor 5 data channels coming from 5 different sensors in real time. I have no options except parallel port with c++. Can i really materialize this without toasting the port ?

Hope that helps with the homework, Peter
