This could be re-written:
"Unlike PCL, PostScript is device independent. that the print quality
is at the mercy of the PostScript interpreter implemented inside the
printer. If they have done a good job, graphic objects will be
consistent and in some cases of higher quality than PCL, but can equally
be terrible if the firmware developer has done a shoddy job."
Really it's just moving the problem. If the PostScript interpreter in
the printer does a poor job of generating the raster image to be
printed, it's going to look crap no matter what.
That does mean that PCL printers do have an up-side in that you can at
least control the PostScript→PCL end of the equation, and if the PCL is
well documented, it is theoretically possible to get good quality output.
