Do you think it is valid for todays printers?
Possibly though, Dual droplet thermal heads already existed before 2000, at least the patents show that. What I recall not that successful in products, and after that a return to one size droplet heads with more nozzles + smaller droplets as the better alternative. Improved MEMS technology for head production made that possible around 2005? Implementing dual droplet size heads in that technology had to be done again I guess, nozzles a lot closer to one another with the risk of interfering. 2008 should describe the improved MEMS variation I think.
