I have a iPhone 4S and a Cannon Printer with AirPrint. I have the printer and the iPhone both on the same network, however I still can't locate the printer on the phone. Works just fine with the laptop on the same network. Any suggestions?

Ok, I honestly have no clue what I did different, I have been at this for two days now, and two minutes after I posted this, the printer mysteriously showed up on my phone and I WAS ABLE TO PRINT FOR THE FIRST TIME!!!! :)))

Now I have to figure out a way to get AirPrint to work in my van! I travel for work, and need a way to print invoices....hopefully I can use the phone as a hotspot and connect them that way?

Ok. I was a bit afraid of that. I have read several post on here, and some say it will work, some say it will not. I'm not really familiar with the mifi systems. Is that a fairly cheap solution?

I hate to do this, but I have to correct you Lawrence. I just connected my printer via the wireless hotspot on my phone. It was a litle tricky, because the first connection had to be done through a laptop that was connected to the hotspot, in order to set the printer up on the same network as default, but not it works perfectly! So it will in fact work! And I can't tell you how exciting that is for me, and how much time it is going to save me! I'm pumped about this!!! Thanks for you time also!

ok no problem! all i did was 1) set up the mobile hotspot on my phone. 2) turn it and wifi on on the phone. 3) connect the laptop/desktop to the hotspot network. 4) insert setup disk for the printer and begin setup. 5) complete the setup "using a usb cord to temporarilly connect the computer and printer" 6) unplug usb cable and finish set up on the laptop/desktop. 7) give it a few minutes to show up on the AirPrint menu on the phone. 8) that should be it. I unplugged the printer and plugged it back in, made sure the laptop was totally turned off AND disconnected from the network, and did everything I could to try and make it not work. The printer I have is a Canon MG3122, it doesn't have a fancy screen or even a way to input a password or anything like that, so it just strores a default network that it will connect to. in order to change networks i would have to complete setup multiple times. Since I only plan to use it with AirPrint for my mobile business....the one network is just fine! Hope this helps!
