I'm in an office that is sharing a printer/copier between two companies. Each company has their own network and ISP.

We'd like to give the other company access to printing (they currently only use it as a copier), but without merging the networks into one.

I wondered if this might be possible using Webtools and IPP? i.e. printing over the net.

What do I need to do to facilitate this? Currently our fiery is on our local subnet with an internal IP ( Can I use port forwarding? Or does it need it's own external IP or domain name?

I've also seen this note throughout all the documentation I read: "For information about setting up user computers to use IPP printing, see Printing. These documents are part of the user documentation set." ...but I can't find this anywhere. Where would I find the "user documentation set" online?
