Could you post the printer definition from printers.conf?
If it's a networked printer, you need to make sure the remote spooler
and/or printer aren't doing any further processing: you want the
raw output from gutenprint sent directly to the printer. This should
already be the case.
The model should be supported by gutenprint:
<printer translate="name" name="Epson Stylus Photo RX680"
driver="escp2-rx680" manufacturer="Epson" model="97" parameters="claria_params"
foomaticid="Epson-Stylus_Photo_RX680" />
However, if none of the developers of gutenprint have never seen
this particular model, the colour balance may never have been tuned.
Or, a change in gutenprint after the model was added may have caused
an unwanted regression in the colour balance for this model.
Firstly, I'd suggest trying gutenprint v5.2.6 from unstable. It's
possible support was improved in the new release. It was added last
weekend. Make sure you upgrade cups-driver-gutenprint, libgutenprint2
and other dependent packages.
If this doesn't improve things, your best bet is to subscribe
to gimp-print-devel mailing list on the gutenprint project site and
ask the developers. They can help you tune it and get the colour
balance right.

Roger
