I am able to share printers on my linux box using cups and they are visible on my networked iPad and iPhone for use. I'd like to do the same thing on the router since it is always on. I've installed optware and can install cups am having trouble configuring. A tutorial including possible dependancies would be awesome!
The issue is (it seems) no one is working on optware packages anymore. The cups package in optware seg faults.
Check out this thread - http://tomatousb.org/forum/t-573238. I got pretty close to a working AirPrint setup, but have since abandon the project and instead went with a PogoPlug running ArchLinux for my AirPrint needs.
If you want AirPlay on your router, try this tutorial I wrote - http://blog.qnology.com/2012/12/tutorial-apple-airplay-on-tomatousb.html
