You're wrong about inkjet vs laser. Laser isn't going to make it in the end; it's all going to be inkjet, most likely pigment based. About markups...toner has massive markup so probably has RA4 paper although I doubt it is as attractive as ink. For now, the only firm we get RA4 paper from is Fuji. Guess who's one of the few major players in industrial inks and print heads? That's right. Fuji... The moment RA4 becomes less attractive to them, they'll push it out and continue with the other horse.

You focus on the highest-end quality part of the market, but the other 99.95% is where the money's being made. They mostly think those measly blacks are plenty black enough.

Anyway, I don't have to convince you. I know what I saw in the industry, and the future of color printing had no silver in it at all.
