HP at London Book Fair, what about Espresso, Blackwells actual Charing Cross Road?

From web browsing I find there are HP meetings at the London Book Fair.

But there is nothing obvious about the Espresso machine as promoted a couple of years ago and bought by Blackwells for Charing Cross Road. I think that Konica Minolto was the basis for that one. HP announced something at IPEX. So what next? The idea of a bookshop as a printing site is interesting. But I can't find any info

any mobile phone to any print device? no problem   but i still think an actual instant book on request by going to Charing Cross Road has an appeal

Sorry this blog is so brief. I am having to concentrate on inxpress.co.uk and the cease and desist letter. So no visit to LBF this year.
