Returning IPP client-error-not-authorized for Create-Job (ipp://IP_SERVER_CUPS:631/printers/MODEL_PRINTER) from IP_CLIENT

[azagramac]

I have installed the avahi-daemon service, cups with the shared option, you can print by cups perfectly, I have created the AirPrint service with the script, iOS detects it, but when I hit print, it does not print.... looking at the log, I find these messages, one after another...
