the "Installing the Windows printer drivers" section can be simplified nicely by using the "cups-windows" package ... this will fetch the latest version from the cups homepage and install the windows binaries in the right place (/usr/share/cups/drivers/)
Thanks for reporting, this closes a longterm known issue with the guide, that of having to use an ancient package I had to mirror on my devspace. Yay for the new way of installing the drivers. Fixed in CVS.
