Exacq Cash Register Text Insertion

Looking for some product help. I have a customer that is needing 3 cash registers monitored via text insertion. He currently has a device that is capturing the DB25 (Printer) cable between the register and the printer and is injecting this data over the analog camera. He is wanting IP camera. What devices out there capture DB25 printer data and turn it into an IP stream? The device needs to be compatible with Exacq. Any suggestions?
