Bonjour printing


I just setup a wireless printer again
When I added printer I had 2 choices either pixma 892 series or the bonjour pixma 892
I tried the bonjour first I got an error, but was able to add the other

I used to be able to print from iphone and ipad to this airprint supported printer but it does not print anymore, but does print from Mac
I read that bonjour needs to be enabled

do I have to add the bonjour pixma 892 printer or can bonjour be enabled somewhere else

When I print from ipad does it go directly to printer or via the Mac to printer

Thanks in advance
