I don't know of any tool to do the job, but it sounds to me like you may
not be using the Ghostscript options correctly. If you're using the
stcolor driver, you should be specifying the stcolor.ps file to be printed
on the same run as and prior to the file you're trying to print. For
gs -sDEVICE=stcolor <more options> stcolor.ps myfile.ps
Red Hat's printtool, just as an example, does *NOT* set this up correctly.
If you're using Ghostscript 5.01 and its new uniprint driver, specifying
stcolor.ps shouldn't be necessary; instead, there are configuration files
for specific printer (including the ESC 600, I believe) that accomplish
the same goal. Ghostscript 5.01 will also handle the ESC 600's 720x1440
dpi mode, which 4.03 and prior versions won't.
In addition, you may want to experiment with different dither modes, since
these can influence the way a printout looks.

AFAIK, the paper selections just set color curves, which is the main task
that the stcolor.ps file handles. I'm not sure what "economy mode" is on
these printers, but on most, it's simply a lower resolution mode that puts
less ink on the page. This can be accomplished with the color curves and
a resolution statement in Ghostscript.
As a practical matter, and AFAIK, in Linux the most convenient way to
handle this is to set up multiple printer spools. For instance, for my
ESC 400, I have four spools: epson180, epson360, epson, and epson720,
which print in increasing resolutions. (The "epson" spool is actually
720x360, and "epson180" is 360x180; the others are squared resolutions as
their names imply.) This works pretty well for me, though it doesn't give
the sort of job-by-job mix-and-match control that's possible under
