if you post photos of the printout with the information you can look up the firmware to see what it belong to. Looking at the biggest molex plug also gives you a clue as to where it could go. If it has an 8 pin female connector, it is most likely a netplex printer that goes into an IGT machine. If it has the bigger 14 pin connector it is a serial printer and could possibly go into a bally, WMS, Aristocrat, etc that use serial printers, it would depend on what firmware is flashed into those to see what they belong to.
