Hi!

The HP has a 25 pin
male connector, and the Netgear has a 36 pin
Centronics connector -- quite different.

Hmmm...the HP printer sounds as though it is a serial printer?

If it is a serial printer, then it is electrically incompatible to the
Centronics connector on the Netgear device. An adapter would have to be
capable of reconciling the differences between the serial and parallel
methods of communication. This can be done, but it may not be cheap.
