Finding network printer, firewall issue?

[jaxom98]

Hello, can anyone tell me where to find the firewall?
OS Edubuntu 12.04.3
It won't detect my printer. (works perfectly in ubuntu 8.04 and win7) I found another thread that was almost the same, the fire wall was set to block all incoming. Result , could not detect printer.
WHERE is the blasted firewall hidden.
There are a number of changes from 8.04 and they obstruct usability

Try

sudo ufw status verbose

That will at least tell you what the firewall status is. It shouldn't be active unless you turned it on.

You can use Synaptic (at least, in lubuntu 13.10) to install gufw, a simple graphical firewall manager. That's how I solved my printer problem.

Without a graphical window, you can edit iptables, according to this page:

As stated, the status command will tell what states it's in.
If using the default setup it will be inactive.
Try

sudo ufw enable

to activate.
Run

man ufw

to get an overview of what parameter you can use to set things

Edit:I realize after re-reading the OP that this thread is about a network printer.
Try this in a browser address bar

localhost:631

which should open up the cups page for you.

Also, the "gufw" program is just the graphical front end for "ufw", the default firewall.

Make sure you have cups installed too.
