I'm sorry, I assumed that it was common knowledge that getting printers setup, especially in a team or enterprise environment, was some of the fucking worst and most annoying work you'll ever run into in IT. That it was common knowledge that proprietary driver bundles and features and whatnot are the bane of any consumer, and that interoperability was a fucking joke beyond the most basic of printing features (if then).
I figured it was also plainly obvious that the article suggests strategic partnerships creating this support, which very strongly indicates that the print support will be either some gnarly plug-and-play driver nonsense or weird stilted API defined by Microsoft.
I'm rather fond of the current "give me g-code I'll emit parts" model, as it is very open and hackable.
EDIT: By all means, downvote me. We all know printing sucks.
