HP Pinout for POWER

I have a HP Printer with that purple power connector from a friend, its untested and i dont want to waste $10 for a adapter and this may not even work... Doesn anyone know the pinout and power for this? I think it states 32v in the back but on what pin? I know pin 2 (middle is gnd) but there are 2 others i dont want to fry this if it does work.

The printer is a officejet 6500 (wireless)

If it's anything like the HP 2280 deskjet, then the voltages are 32V/375mA and 16V/500mA.

My officejet 4500 has the same connector

This is straight off the ac adaptor.


+32 .... Gnd ...... N/C

Thanks!
