I have connected a USB printer to my airport express terminal (Canon MP170).
My PC and Mac (OSX Lion Mountain) can see my printer and I can print, but I do not see my printer on iOS (iPhone 4 and 5)
For cons, I downloaded the application pro printer and there I see my Canon ...
where is the problem? the age of my printer ?
Thank you for your help.
Canon has an app for its' printers https://itunes.apple.com/us/app/canon-easy-photoprint/id331269951?mt=8 - but I don't know if it will work for your printer - also check this link http://support.apple.com/kb/HT4356 and this link for a Printopia free trial.
