Failed to communicate with the printer.

[lucasahall]

From all of my apps (android and iOS) i get this stupid error.  

"Failed to communicate with the printer.  Check Printer connection.  If there is no problem with the connection, open your smart phone's settings and check that this app has been granted local network access."

I can print just fine from wired devices such as my home PC and also from a wireless laptop.  It is just not working for my apps on myy phones and tablets.

I have uninstalled an reinstalled on the phones and tablets.  I have removed the printer and reinstalled it on windows.  I have checked the print queue as well as the spooler.  The connection is just fine with the printer as I am a wireless network engineer.

So why does this Canon Print app suck so bad?
