Howto: AirPrint in pfSense 2.0
-
Adding AirPrint to pfSense 2.0
iOS devices(iPhone, iPad, iETC…) can print to the CUPS service previosly set up in pfSense (See my other tutorial http://forum.pfsense.org/index.php/topic,44941.0.html ).
Steps:
1.) Install "Avahi" from the "Packages" screen in pfSense.
2. ) Install dependencies:
pkg_add -r gutenprint-cups py26-cups
3.) Go to: https://github.com/tjfontaine/airprint-generate/blob/master/airprint-generate.py and copy the code to a text file "airprint-generate.py".
a.) Change the first line in the file:
#!/usr/bin/env python
to
#!/usr/local/bin/python
If you did this in windows you may need to run it through a dos2unix conversion. I used.
The one available here. Just dodos2unix.exe airprint-generate.pyin the windows console.4.) Generate your printer service config for Avahi:
./airprint-generate.py (This will output a file for every printer setup in your CUPS server)
5.) Remove all default service files under: /usr/local/etc/avahi/services/ :
rm -Rf /usr/local/etc/avahi/services/
6.) Move your newly created *.service file to /usr/local/etc/avahi/services/ :
mv *.service /usr/local/etc/avahi/services/
7.)
chmod 755 /usr/local/etc/avahi/services/*.service8.) Edit the default avahi-daemon.c template so that /usr/local/etc/avahi/avahi-daemon.conf is overwritten with our custom config whenever the service is started/stopped.
vi /usr/local/pkg/avahi.inc
Comment out:
#host-name={$hostname}
#domain-name={$domain}
#browse-domains={$browsedomains}9.) Add "ServerAlias *" line without the double quotes to /usr/local/etc/cups/cupsd.conf like so:
Allow remote access
ServerAlias *
Port 63110.) Now from here you can just reboot the router. Or you can continue with manually restarting services.
11.) restart cups:
/usr/local/etc/rc.d/cupsd stop
/usr/local/etc/rc.d/cupsd onestart
12.) Disable, then Enable Avahi from the Services menu.
a.) Be sure that your local domain is listed in the "Browse domains" field. (mine is localdomain)
b.) Select WAN in the "Deny Interfaces" field just to be safe.
c.) uncheck "Enable" and save.
d.) check "Enable" and save. (But you probably already guessed this part) :p
That should do it. Now try and print from your iOS device while it is on the pfSense router LAN.
I do believe that you will need to have an iOS 4.2 or higher device from what I am reading.

Here is the most current version of airprint-generate.py from the time of this post. Just in case the original link goes away.
Give props to Timothy J Fontaine for the script. I did not create it. https://github.com/tjfontaine ;D
