Hello all, I recently upgraded my iPhone to iOS 4.2.1 and wanted to try the so called "Air Print" function. It's actually IPP printing coupled with Bonjour service publication => it's all handled by my Duo and the I'm refering to a very interesting blogpost here I went as far as making the printer connected to the Duo visible for the iPhone : I made the required changes to /etc/avahi/services/printer.template then unplugged & replugged the printer. Unfortunately, its not sufficient : the cups queue needs to support PDF.
I went further to install cups pdf but I stopped dead when seeing the following output :
ReadyNAS:/etc/avahi/services# apt-get install cups-pdf Reading Package Lists... Done Building Dependency Tree...

Need to get 11.7MB of archives. After unpacking 16.8MB of additional disk space will be used. Do you want to continue? [Y/n]
So my question is : Regarding the fact that some packages would be removed (why remove samba btw?) do you think it would be safe ?

As you can see there is "samba" on the list of packages to be removed. So if you want to loose connectivity to your shares, you may say "yes" - otherwise "No" would be the better choice 😄
Rule of thumb: If apt-get displays anything about "REMOVE" just say "NO" to whatever question follows.

Thanx Stefan, that's what I thought.
I went further in my investigations : cups-pdf is not actually needed. What's needed is a filter able to convert PDF format to printer format (cups-pdf being a virtual printer driver generating PDF files). It's actually a good news (or may be not : it means I'll have to learn a lot about cups before being able to do something)
Did you manage to get this working as I am also interested in making the ReadyNAS attached printer visible on iOS devices?
Well, I think everybody gave up this subject for the time being. Once again, we're faced with the *antic* version of kernel and OS. Basically we need modules we cannot have to actually print (we know how to make the printers visible to iOS).
