Eclipse Computers in Coventry do a 2 parallel printer PCI card for £6.95
BUT
Although I have not had any problems with them, they have a terrible reputation for customer service (Google them !).
I used one of these cards, but it needs setting up properly. (I am going thru a Senior Moment phase 'cos I can't remember what I had to do).

Anyway, that card is a Netmos 9815. It is still in the computer but drives LPT2 and LPT3 and I have plans for putting in a second BOB to do limit switches or move some functions to that BOB and do the limit switches on the main BOB (which has 12v as I am using inductive switches).

Having said that, I now have a Motherboard with an onboard Parallel Port and this connector may be all you need Shiny Hardware Limited
They also do a PCI parallel port card.

Anyway, it is time for my medication now and the nurse says I have to put the computer away
