[cups] AirPrint on Linux not on OSX

[Sy Bensky]

Hi,

Earlier this year - with help from the on-line CUPS Discussion group - I was able to 
figure out how to register my two non-AirPrint printers (HP LaserJet 1200 and Samsung 
CLP-300) as AiPrint capable on a PowerMac (OSX 10.8.3) using dns-sd.

Last month I installed Ubuntu Linux 14.04 on a spare PC.  I went through the install and 
customization and installed to two printers.  I printed the test pages to verify that the 
printers were installed correctly.  There was nothing about AirPrint in the printer 
install dialogs.

Later that day I was printing something from my iPhone and discovered that somehow Linux 
had registered the two printers as AirPrint capable.

Since Linux and OSX use CUPS as the printing system I became curious as to why AirPrint is 
supported on Linux and not on OSX.  On Linux, Avahi 
(http://en.wikipedia.org/wiki/Avahi_(software) is the zero-configuration networking 
implementation for multicast dns-sd service discovery.

I downloaded the CUPS 1.7.5 source code and scanned for references to Avahi.  One of the 
references returned by grep is the following:

/Downloads/CUPS/cups-1.7.5/cups-1.7.5/CHANGES-1.6.txt:	- CUPS now supports Bonjour using 
Avahi

My question: if CUPS supports Bonjour on Linux, why does it not support Bonjour on Mac OSX?

Sy
