Modern Inkjets And Linux Support?

Clinton Work asks: "There are tons of cheap/high quality inkjet printers on the market, but all of them use proprietary Windows printer drivers. The older HP inkjets have Linux drivers but are no longer on the market. Your only option is too choose a more expensive inkjet or a cheap laser printer with postscript support. I have looked at the modern printing software like LPRng and CUPS without any luck. Does anybody have a solution?"
