Here's how I set it up - not sure I have the right driver yet but it appears to work:
- go to System Preferences > Printers
- add new printer
- click the button at bottom "More Printers"
- choose Windows Printing, browse Network to find the WL-700gE
- select the printer!
My printer is a Canon i550 that unfortunately, OS X refuses to show the driver for it when setting up to print via network. Chose the BJ7100 driver for now, it prints but I'm not sure it is printing 100% optimally; initially, the colors seem to be screwy.
