I am trying to set up iPrint for a Deskjet 6127 which has a Network
card in it. I can ping the printer but when I set it up in NDPS as an
iPrint printer, I get the error 'LPR Communication Failed'. Other HP
Laserjet printers that are set up on the same print manager work fine.

I would have thought that since it has a built-in network card that it
would support iPrint printing and the IPP and LPR protocols. Does
anyone know if it does or not?
