This email is to thank the developers of the foozjs driver and the http://foo2zjs.rkkda.com/INSTALL.osx
page (Rick Richardson).
It worked perfectly in the first go!
Only thing i noticed is that the command in 6a) http://foo2zjs.rkkda.com/macosx/
(Print\ Center.app) was not present on my MAC.
Instead I just opened the Printer & Fax in System Preferences, and the printer was shown with the driver (basically the GUI shown in 6a)).
