I'm adding an "AirPrint" extension to my enhanced Raspberry Pi image (which already has facilities to allow SSH, VNC servers, FTP, and a Webserver).
It is basically working, the Avahi service permits IoS devices to 'see' the non-Airprint prints as if they are Airprint Printers and I can print the first document after a cups server restart. However, not a second over the network. Local test prints are fine.
Essentially the cups network service seems to 'lock'.
A cups restart clears the problem.
I've used a similar technique on PC Linux without seeing this problem- it seems to be a R Pi issue.
Has anyone on the group been experimenting with this?
(I have Googled this to death BTW).73 Brian
