Many of these printers don't work well on Free OSes unfortunately. Or require binary blobs (looking at you Canon) that are barely maintained piece of software cobbled together...
Why don't we have a common interface for printers. Something you could just push a simple pre-processed postscript or even bitmap. And then the device would do the stuff it needs to print it. Have basic set of options in there, page size, duplex, etc...
They likely already have enough processing power for that anyway...
I had an HP and Lexmark working with Ubuntu and didn't have any problems that I can remember. I still imagine the market demand is quite low, especially if there are some existing printers that already work.
I guess I could see it if it was DIY. But then the question would be why it hasn't been done already.
