Access print server through firewall?

Question

At my workplace, we have two fiber networks setup, one for the business network and the other for process control (industrial manufacturing). On the business network, there is a standard print server that all computers on the business network can access.

On the process network side, we would like to be able to print on the business network printers, however, I am stumped as to how I would do this.

I should mention, that the business and process network each operate on their own domains and are separated by a firewall.

Solution

As others have said you can open port 9100 on the business network firewall so the process network can print to the printers in the business network.

What no one else has said so far though was to make sure you build you ACLs on the business router to only allow port 9100 traffic from the business network and no other IP addresses and make sure your NAT rules are configured properly.

Take a look at IPP. It uses a single port and should be easy to set up through a firewall. Or, but another printer...

I haven't had a chance to look into it yet, but would it require that I setup a print server on the process network side?

Yes, but the printer could have the print server built in.
