Sometimes you just have to know when to give up. I've been trying to figure out how to get my wife's Linux box to print on the printer I've hooked up to my OS X box. I configured the printer. I set up printer sharing. I connected to the CUPS server locally without problem. Then I tried to connect remotely. No luck. I edited /etc/cups/cupsd.conf to add the IP address of the linux box. No luck. At some point you just have to know when to give up. I give up. If there is a way to get printer sharing over IPP working with an OS X box as server and a Linux box as client I can't figure it out.
