Adding a printer (local or network) was a mistake. Define the default
printer is the problem.
The situation: going somewhere with a laptop and plugging a printer
there. The printer is automatically added, OK. But it is not the default
printer automatically and if I don't want to print using

lpr/dvips/whatever -Pnewprinter

I want to define for sometimes this printer as the default one. In that
case the cups web interface (http://localhost:631) asks for the root

I want to get rid of this. I did not know the: System>Hardware>Printer!

No; I just wanted to say that was the only possible configurations I
have found, and maybe had missed something somewhere...

This is not clear for me: I have a private lan with one server and a few
clients and if the httpd server is running on the server, a request
http://localhost:631 on a client, automatically switches to

And I don't know why and I don't know how to avoid this behaviour.

Thanks for attention.
