How can I stop firefox auto discovered printers on fedora?

On Linux Fedora (19 & 20 at least, probably others) Firefox automatically detects printers connected to the network, completely independently of CUPS. The printer it finds for me is legitimate, but it does not install the drivers to make it work properly. If this printer is used, it will display gibberish; control of PDF language, sometimes total sometimes undesirable. It restores the right page and tons of paper waste.

Thank you!

Thank you.

I found that avahi-daemon is the culprit. I just do a fresh install of Fedora 20. I have not configured all printers, and yet the printer 'bad' appeared in the list of printers in Firefox. After that I stopped avahi-daemon and avahi - daemon.socket, the printer went away.

I also noticed with my installation of Fedora 19, bad printer went if I put my computer on a different subnet.

So the next step is to understand how to configure avahi to not behave in this way when it runs.

I appreciate your help.

I looked at what I could find on avahi, but seems not be one any affecting to ignore a particular host. However, after a survey, I found the right setting on my Lexmark E260DN to change. Under TCP/IP settings, there is a checkbox for "mDNS." The default value is on. Once I turned it off, that solved the problem, allowing me to reactivate the avahi on my computer safely. I had looked for something like this earlier, but missed, I was looking for things like 'Hello', "zeroconf", "DNS - SD" or something similar.
