Right. PostScript is *page* oriented and *Inkjet* printers are generally NOT
*page* oriented -- they print some number of dot-rows. Inkjet printers are
really just high resolution dot-matrix printers and from a software /
interface point of view are *exactly* like the old dot-matrix impact printers
of yeateryear (just no actual "impact", no ribbon, many more "dots" and
generally 3 or 4 colors).

*Laser* printers are *page* oriented and many Laser printers support 
PostScript.
