How do I print to a remote CUPS printer

On the remote machine, FC5, I am root.
On the clients, FreeBSD and FC3, I am not root,
but can open TCP ports.
Is there a nonroot IPP client that can
be used to print on a remote printer?

On the CUPS server you must make the print queues shared. The clients'
CUPS will automatically see the shared queues on the network.

On the server, go to System->Administration->Printing, click on the
queue you want to share, then Edit, etc.

Oh, and you must have port 631 tcp and udp open on the CUPS server.


That is absolutely the wrong way to share printers using CUPS. All printers on the same lan as the server can
print to the server's printers by default. No configuration is required.

And exactly why is it absolutely wrong? It works flawlessly on
my lan. And in fact if I don't make the queues shared on the CUPS
server, they are not automatically seen by the clients. Of course,
I can tell each client separately about the address of the server,
etc. Of course the clients on the lan can print to the server's
printers by default, if the server tells the lan about its printers.
That is, if the printers are marked as shared on the server.
Am I missing something here?


Well I absolutely should not use the word absolutely so loosely. There
is not such a thing as marking a printer as shared under CUPS. That is a
construct that system-config-printer has brought over from the pre-CUPS
era. The printer server sends out browsing information to all the
machines on the lan and the clients become aware of the printers
available to them from these browsing messages of printers that are
available.

So let's not get entangled in semantics. The fedora printer config
utilities use the term "shared" for all you said above (which is
correct).

If you use the web interface on the clients you will see the
printers on the server which have been browsed. All CUPS printers should
be configured using the web interface.

Says who?

No marking printers as shared is
necessary.


What if I don't want a printer to be seen by some/all clients?

The most flexible way to configure the printer is probably by
editing the config files by hand. At first I thought you were trying
to suggest a different configuration of the cups server. I see now
(as I suspected) that you're only suggesting a different interface
for configuring the same thing. The interface is off topic here.
The man wants to know how to print from downtown to his home printer.
