Hi Folks, I Have an Ubuntu Cups Server, with a Lexmark E210 connected to it. From my Ubuntu Notebook I print very well through this server. But, my sister has an Apple Notebook, with OS X. I tried to configure this machine by ipp, address 192.168.1.100:631 and queue /printers/lexmark. But it just doesn't seem to work. Thanks for your time, Joao Mario.
