Firewall ports for iPrint

If your iPrint server is behind a firewall what ports do you need to make
sure you have open in order to allow clients to print and to be able to
communicate with the printers? I'm setting this up in a test environment
and my print manager cannot contact the printers even though it can ping
them.

I believe port 631/tcp.

Re: Firewall ports for iPrint

Well, from the description, it looks like your firewall is between the
server and the pritner. In that case, you have to open the printer
protocol used for printing. This is port 515 for LPR or port 5100 for
"raw". Also, if you want the query the status of the pritner as well, you
have to open the SNMP port. I don't remember the port number for it.

SNMP is udp port 161
LPR is tcp port 515
RAW is tcp port 9100

Of course this is assuming the firewall is between the printer and the
server. The way I read the OP, the firewall is between the user somewhere
out on the Internet and the internal LAN--but the server & printers aren't
firewalled from each other. If that's the case, then neither 515/tcp nor
9100/tcp would have to be opened.

That's true, but as I already mentioned in my first reply, the customer
notes the following:

This suggestions a lack of communication between the server and the printer.

If you are using secure printing you need to open TCP port 631 (this is
what I did for my environment). This is the default iprint port to
fource authenticating access to the iPrint WEB page.

Is that port 9100 for RAW?
