Industry historians, too, will find the 20-year history of the Deskjet quite interesting. It's a timeline with much more detail than most similar pieces include. Must study!
Interesting too, despite the focus on the Deskjet, is the news focus on expanding to retail photo printing, an example being the AP story by Amanda Fehd, "HP Looks to Stores for Inkjet Expansion". There's a tone that home photo printing is in major decline, its golden age having passed some time ago. I'm not sure I'd be quite so harsh.
Five to seven years ago, the majority of digital photos were printed in the home, according to Federico De Silva, an analyst with Gartner. Now 60 percent are printed at retail outlets.
