This is what i did for my Canon MX850 to get AirPrint working on my Ubuntu system.
1. Have a Standard install of Ubuntu Desktop.
2. Go into the CUPS interface and make sure “Share published printers connected to this system” is enabled on the server settings.
3. Install avahi-daemon and make sure it is running.
4. Install avahi-discover and run it from a terminal. Click the printer you wish to duplicate. You should get something like:
[code]
Service Type: _ipp._tcp
Service Name: Canon MX850 @ Saturn
Domain Name: local
Interface: eth0 IPv4
Address: Saturn.local/10.0.0.4:30466
TXT Binary = T
TXT adminurl = http://Saturn:631/printers/Canon-MX850
TXT Duplex = T
TXT Copies = F
TXT Collate = F
TXT Sort = F
TXT priority = 0
TXT Fax = F
TXT rp = printers/Canon-MX850
TXT ty = Canon PIXMA iP5300 – CUPS+Gutenprint v5.2.6 Simplified
TXT Punch = F
TXT note = Saturn
TXT printer-state = 3
TXT txtvers = 1
TXT Transparent = T
TXT product = (Canon PIXMA iP5300)
TXT qtotal = 1
TXT Bind = F
TXT printer-type = 0xB01E
TXT Scan = F
TXT Color = T
TXT pdl = application/octet-stream,application/pdf,application/postscript,image/jpeg,image/png
TXT Staple = F
[/code]
5. Create file name /etc/avahi/services/mx850.service.
6. Create an XML file similar to the example below, using the data above as the values.
[code]
< ?xml version="1.0" standalone=’no’?>
< !DOCTYPE service-group SYSTEM "avahi-service.dtd">
<service -group>
<name replace-wildcards="yes">AirPrint MX850 @ %h</name>
</service><service>
<type>_ipp._tcp</type>
<subtype>_universal._sub._ipp._tcp</subtype>
<port>631</port>
<txt -record>txtvers=1</txt>
<txt -record>qtotal=1</txt>
<txt -record>rp=printers/Canon-MX850</txt>
<txt -record>ty=Canon PIXMA iP5300 – CUPS+Gutenprint v5.2.6 Simplified</txt>
<txt -record>note=Saturn</txt>
<txt -record>product=(Canon PIXMA iP5300)</txt>
<txt -record>printer-state=3</txt>
<txt -record>printer-type=0xB01E</txt>
<txt -record>Transparent=T</txt>
<txt -record>Binary=T</txt>
<txt -record>Duplex=T</txt>
<txt -record>Copies=F</txt>
<txt -record>pdl=application/octet-stream,application/pdf,application/postscript,image/jpeg,image/png</txt>
<txt -record>URF=none</txt>
</service>
[/code]
7. Save the file. avahi-daemon should notice the new file and load it without a needed restart.
8. Add the following to /etc/cups/cupsd.conf near the top
[code]
ServerAlias *
Port 631
[/code]
9. Restart CUPS “/etc/init.d/cups restart”
10. On your iPhone/iPad, go into Safari, print, and search for printers. Your new printer should be in there.
—————————-
Update: as of June 28, AirPrint is built-in on Ubuntu 11.10.
1. On your computer start system-config-printer via System ->
Administration -> Printing (GNOME Classic) or via Turn-off-button at the
upper right -> System Settings -> Hardware -> Printing (Unity Natty) or
via the command line (all systems including Unity Oneiric).
2. In system-config-printer choose Server -> Settings and activate
“Published shared printers connected to this system”. Click OK and then
right-click on the icon of your print queue and choose Properties in the
pop-up menu. In the Policies section of the dialog make sure that
“Shared” is activated.
3. Make sure your mobile device is accessing your local network using
WLAN and then open an application with printing functionality on it
(like for example the browser or the photo viewer). Print something. The
print dialog should show your print queue and allow some basic settings.
Note that the Description/Info field and not the name of the queue is shown.
4. Check whether you get a correct printout.
