Actually, my opinion is that HP may be kidding themselves a bit on much of this. Print buttons on blogs? We've survived without them so far, so that should tell us something! And back to that 48%? What happened to all those camera phone photo prints? Seems like they'd be the dominant source of home printing, based on predictions of the last few years. The world is changing, or more accurately, the world has already changed. Print "ain't what it used to be" and will play a diminishing role in the future, at least as a proportion to all information shared. You read it here first!
On this theme, HP's LaserJet blog covers similar topics but also reaches, in my opinion. Vince Ferraro mentions Scribd in his latest post, "LaserJet Printers in the Web 2.0 World", as I've covered previously in early March and April. But in my opinion he's also stretching it when he states "I like what they are doing because they are essentially trying to create the YouTube equivalent for documents and this content ultimately needs to be printed". No doubt, some of those docs will be printed. But many will be shared in other ways.
I prefer a broader view of printing as a part, and only a part, of ever-changing information flow. HP is wiser to stick with that thinking as the foundation of its strategy, as Vyomesh Joshi is quoted in the PC Magazine piece I posted about yesterday:
While we are very successful, I want to transform our business, it's not about the means, it's about the end. It could be making DVDs, printing, or viewing. Build on our core competency, and move our organization.
