I promise you that you will not get 600 dpi if you set the `Quality' parameter to `2'.
As the documentation, which comes with HPIJS, tells you that you can yield up to 600 dpi.
You have to use the HiRes mode (Quality = 3) to get 1200 dpi.

I've attached a small shell script which converts Postscript to the DJ970 code using Ghostscript.

You will see that you'll the error message:
	unable to SetPixelsPerRow width=9601, err=26
if you try to get 1200 dpi with Quality=2.

Have a try!

Your "best output you've ever seen" might come from scaling by factor two,
or an enhanced algorithm in the new HPIJS.
