Yeah and those drivers did all the rendering on PC before sending it to the printer as a bitmap: another way to make the printer cheaper. Good office ones spoke PS and let you offload the PC immediately.
I'd be sufficiently happy if a printer just accepted writing bmp/gif/jpg/png files to it, because then monsterous proprietary printer drivers wouldn't be necessary. "WinPrinters" were supposed to solve this, since Windows' GDI could do the rasterisation itself (and for non-Windows, similar libraries exist), but clearly that didn't work out. Cheaper, dumber printers with simpler firmware are not a bad thing at all, both for the user and the manufacturer. Unfortunately the latter are more interested in hostile "smart" crap.
