It would seem that the standard for mobo headers for PPs is as Tweakie said and in the above drawing so I would think the eBay one would conform as well. It is correct that way as the pinout in the manual confirmed that, you can do a google for printer port pinout and you will see it matches if you go along the rows of the IDC header rather than by the numbering on the mobo.
Easiest thing to do is open a new profile, put the address for the onboard port in and set up an output for coolant to pin 1 and set the relay up for the coolant to that output number on the spindle setup page. You can then toggle the coolant button and have your voltmeter on pin 1 and pin 25 of IDC and see if voltage changes, if it does then you know the port is working fine.
