*** As of IOS 6.1 , CUPS airprint functionality is broken. There is a lot of stuff on the web on how to make it work but I am not gonna use it. I’m just gonna wait for either Apple or CUPS fix it. *** -rafiks
***** I found a solution to the IOS 6 problem with Linux Cups. Basically, the source of the problem is that IOS 6 changes the output of the print file from PDF to URF . I found this howto from this blog http://thepoch.com/post/32724116678/get-linux-airprint-working-again-for-ios-6 . .Thanks to the author. The only difference is I did a /etc/init.d/cups restart and /etc/init.d/avahi-daemon since I use Debian. *****
**** Good news! As of today 2-28-13, CUPS 1.5.3-2.15 from debian fixes the problem. No need to do the hack mentioned above. I love Debian! ****
This is a followup to this post . Thanks to one of my readers I had to revisit this and make a few changes because it wasn’t really very clear. I will add some screenshots to make this easier. First off the,the original article was for a stand alone cups printer server which I installed on my sturdy Linux Box. For this how to,I am using my Macbook Air as my Cups server.
Ok . Here’s the recipe. I tried this one on a:
- Macbook Air OSX 10.8.2
- Ipad 3
- Brother HL-2270DW
I connected all of them via wifi. So obviously they need to be all on the same local network. Airprint or CUPS still doesn’t work over the internet which would have been fantastic.
1.Turn on the printer and go to System Preferences > Print and Scan 
2. Add a new printer . The printer should appear like so :
3. Add the printer that was discovered and choose a generic PCL driver.
4. Save the new printer
5. Go to the Terminal app and edit the ppd file of the printer you just created . It is found at the /etc/cups/ppd.
6. Your PPD file should look like this. I only edited the highlighted parts. I use that HP model because that’s the one working for me. It really doesn’t matter as long as it’s an HP because that’s the only brand that works for the Coupon app.
7.Open your Iphone/Ipad/Ipod, check your Safari and Coupon’s app. Your printer should appear on the choices.
