Nat,

If I correctly understand the web site both parties (or all parties) need to
have the application installed; it's not hosted on a server somewhere.

Yes, this is a continuation of the original issue.

To recap:
About six months or so ago I replaced my router, which required changing
the IP address on my printer. After the IP address change, the print became
washed out with a yellow/greenish tint. At first I thought it was a printer
problem. Later, I discovered that it printed fine from my other computers.
It was suggested several times it may be a driver problem. I had asked how
to update or otherwise fix the driver problem, but got no replies. I got by
with it for a while as the colors were not a big issue at the time.
Recently, I had to change routers again, with IP address changes as well.
>From several other sources I was recommended to visit a web page that
discussed updating hplip. I followed the instructions there and installed
the latest version of hplip. The installation removed the previous version
of hplip and my previous printer information. Following the listed
procedure, it progressed fine until it started the printer install. Once it
discovered my printer, it said a special binary plugin was required and
proceeded to install it. The installation was successful, but it again said
the binary plugin was required. This repeated a number of times, plugin
required, install plugin, plugin installation successful, plugin required,
install... ad nauseum. Some Internet searches revealed many people had
experienced this behavior over at least eight years, but the complaints
were never answered or solved.

So, I tried to use cups and skip hplip. The various instructions all say to
go to localhost:631 for the web interface to cups. I verified cups is
installed and running. When I bring up the web interface, the opening pages
displays fine. However, any local link I click on simply goes to a page
that says "Not Found". Remote links to forums, cups websites, etc. all work
fine. There are a variety of help files, which I located at
/usr/share/cups/doc-root/help/. I can browse directly to that folder and
display the various helpfiles directly, but not through the localhost:631
home page. The  add printer command Adding Printers and Classes
(localhost:631/Admin) also says not found.

Now, neither hplip nor cups seem to be able to add my printer and I cannot
print at all from this computer. I think my next step might be to try to
remove hplip completely and reinstall cups and go that route. My other two
Mint computers do not seem to have hplip installed but only use cups and
they print just fine.

We'll see.

[Mike C.]

Rich, yes by definition Peer to Peer connections and distributed networks
don't require a central server.

However, if NAT is involved between 2 peers a TURN / STUN server is
required to handle NAT traversal. As most endpoints are behind an ISP or
company router/firewall with a private IP address a TURN / STUN server
would almost always be required.

But individuals.can run their own TURN / STUN servers at home and/or work.

I'm not sure if OpenWRT has this functionality. I suspect it does.

Jami also has an account management server which would be good and useful
for large organizations.

The Jami website has some pretty easy reading blog posts on all of the
above topics.if you're so inclined.
