Apple update causes print problems with Bonjour printers

On the 30th March 2013, I installed apple updates for Bonjour & Bonjour Print services on my Windows 8 computer. I was then unable to print from that machine. I ran the Bonjour Print wizard, but it could not find any Bonjour devices. My apple Express and Time Machine were visible from my Apple computer & Windows XP machine & printer workked OK,

I have now restored the Windows 8 computer to a date before I installed the updates. I ran the Bonjour wizard, it recognised my printer which now works

I need to install ITunes, but I see from correspondance on the web that this will reintroduce the Bonjour printing problems.

Is there any solution to this ?
