Hi

I have some rather old equipment which is currently transmitting data to a line printer which then simply prints this output, there is no way for me to change the way this output is given so what i need is to read the data transmitted to the printer. Meaning i need to read from the parallel port ???

How can this be done ?

That should do it.


Alternatively, get a hold of a parallel to serial convertor and then read from the serial port (easier).  What do you want to do with the data once captured?

A good question. I'm assuming that as this is an old parallel application then we don't have to worry about ECC. I'll have a dig around and get back to you.

You could try one of these, but make sure of your application first. http://commerce.patton.com/pe_products.asp?category=148
