Brother printers (at least some) support BR-script which is Postscript without the trademark violation. It's supported at the driver level, I think, which would render the PS on the PC then send the rendered document as one of the hardware-supported languages like PCL.

I mention this as an interesting bit of info, and not to refute anything you said
