JetDirect card for 4600dn Color LaserJet

[AlexB6]

I have an old Color LaserJet 4600dn  that has a broken JetDirect card in it  (615N).   the original docs say that the printer came with a  610N.   the newer info on the HP site says that a 620N will work.   Question:  which item do I buy..?   Are there firmware considerations on the printer side, that may limit which JetDirect will work in my printer..?

610N 615N 620N 625N 630N they will all work, the higher the number the newer ( better/expensive) the card.

625N will do just fine, the 620N and lower models can fail more often, the 630N and 635N are expensive.

Thanks!  ---from what I read, the 630N and 635N are wireless cards?    --Wireless is forbidden in my particular environment, so the JetDirect must be  wired.  With this,  It looks like the 620N  or 625N might be my best bet..?
