I haven't read the article or the MS release but from experience the big distinction is between inbox drivers and those you download from the vendors website. Inbox drivers are drivers that come bundled with Windows or more recently automatically downloaded by Windows. The device manufacturers provide the drivers but Microsoft is fairly strict on what they will accept. More recently they have been forcing the manufacturers to switch to V4 (XPS based) if they want their driver included "in the box". My guess is this is a further tightening of those rules. It indicates the general direction Microsoft wants to move with printer drivers but it's a slow process. I expect your will be able to continue downloading the existing garbage that nearly every printer manufacturer provides.
