If IPP is HTTP-based would it be possible to print directly from the brower to the printer, regardless of OS?

That would be kinda cool or am I misunderstanding something?

If your printer for example supports IPP and Postscript or PDF then that would be possible. Higher end (commercial) HP printers usually offer this functionality. Take a look at CUPS [1] if you want to know more about IPP.
