Interesting article on HP inkjet development



#2

The spring 2001 issue of Invention & Technology has an interesting article describing HP's development of inkjet technology. It talks about the need for a good calculator printer as being their primary motivation and discusses several calculator projects in conjunction with the printer (ultimately the HP 2225). It also mentions a prototype "pocket plotter" that was made for use with calculators by the same group of engineers that created the HP-35. It never got built but lead to the development of the grit wheel plotters.
