I'm at a friends house for a few days, he just bought a Lexmark X6575. He has an older macbook Pro, and I have an aluminum MacBook, both with 10.5.6. We can both print using the USB cable fine, and have ran the wireless setup thing that came with the driver. The green WiFi light on the front of the printer is on, meaning it detects the network. It says "no configured computer found on network." My question is, how do I configure my computer? I can't find anything in the documentation with the printer. If I type the printer IP into safari, it sees the printer and seems to show everything is normal. I've never done this before, so I apologize if I'm missing something obvious.
