I'm having troubles getting this model to work with iPrint.
The server running all the iPrint services has NW 6.5 SP3 installed.
iPrint client is 4.05.

I can add it just fine, and drivers as well, but it tells me LPR
communication failed. Now this is normally just down to the printer having
wrong port, but the same port that works if I add it in windows, doesnt
work via iPrint. I've tried: PASSTHROUGH, RAWx, 9100, L1x etc, and none of
these work. If I go through Windows, the printer happily accepts jobs on
most of the ports. Any ideas?
