And what are we supposed to do about this:

ColorSync is selected, greyed out, and there's no option for "no color management" in the printer driver.
Hi Mobius strip and Gerry Mander,
OK printing from Photoshop:
In Mobius original post it showed that they were using printer color management
which is why they were seeing that warning about avoiding colorsync colour matching -
it's referring to the printer driver options, NOT the Adobe print window. Adobe don't know what settings you selected
there in the driver.
if I select EPSON color controls under color matching as shown below -
I should not see the warning about the dangers of colorsync when clicking save:

BUT if I select colorsync under color matching in the driver as shown below,
I see the warning, also shown below, after I click save


If you hate seeing the warning, you can always click the "don't show this again" box!
but it's there to protect you from wasting ink and paper should you inadvertantly leave it set to colorsync as above.
[Gerry Mander - I can see looking at your conversation with Adobe that the helper didn't truly grasp your situation. Frustrating for you]
Mobius - posted again Jan 24, with a new screenshot and asked:
"ColorSync is selected, greyed out, and there's no option for "no color management" in the printer driver.
- to get that greyed out dialog you must have now selected Photoshop manages color (see below)
so, your situation is different to your original question, to explain:
When Photoshop manages color [and, I hope, a good printer profile] is selected,
then Photoshop can take over & grey out the Colorsync and PRINTER color controls options inside some print drivers
with some printer drivers it doesn’t manage this
So this is pretty much what you are currently seeing, right?

So, with some printers, but not all, those 2 color matching options showed (as above) are greyed out -
which means that if you select Photoshop manages colour Photoshop's making the choice there for you -
to save confusion, its done greyed out the options
that appearance is based on your choice between Photoshop manages colour & printer manages colour
however, you may see a warning about disabling colourmanagement in the printer software -
because there is another place where colourmanagement can go wrong in the printer software -
it's under the printer settings tab (see screenshot below)
hence the warning you may see about switching off colourmanagement in the driver
Please see Epson driver screenshot below, as you can see, Photoshop was set to Photoshop manages color
In the case of my Epson 4900 printer driver, Photoshop has done this important step for me too
- under Color Mode here, the correct option of "Off (no color management)" has been selected
(and the dialog is greyed so I can't get change it and get it wrong, meaning I can ignore the warning).

BUT not ALL printer drivers behave so well, with some machines you have to track down and turn off any reference to colourmanagement / ICC profiles etc. Which is why Adobe may give the warning about printer color management when using photoshop manages color.
Photoshop's warnings are by necessity somewhat generic. There are a LOT of different printer drivers out there.
I hope that explains?
BTW
If you want decent printing from that Epson I'd get a good custom printer profile made.
Using the printer colourmanagement isn't always successful, especially for those not using a paper that’s listed in the driver's media options.
I hope this helps
if so, please do mark my reply as "helpful" and if you're OK now, please mark it as "correct" below, so others who have similar issues can see the solution
thanks
