Sorry for the delayed update, but perhaps I can add some useful information to this thread: To print allowing PhotoShop to manage color under Mac OS10.6.x look into resetting the colorsync-utility default color profile -- details below.* (First make sure you are not using a Gutenprint driver.) 

After setting up my friend's Mac OS10.6.2, we get accurate color managed prints from PS using a custom profile for his R1800 via USB, and the Epson Driver v6.12. 

grandpollo, I have two R1800s at work. I'm not sure how to interpret "old, slow mice where you print"-- personally I'm not using 10.6 -- in case that's colloquial slang referring to an older OS.  Indeed there is a wide gamut of "hue and cry" over color printing in general, and targets in particular. 

At the bottom I repeat some of Myron's post outlining the limited driver option settings in printing from OS 10.6.x.

* Under OS 10.6.x Colorsync chooses a default manufacturer's profile for your printer, if you select another it turns it off. This seems to allow the application to fully manage color.  Launch the colorsync-utility, click the Device icon, go into Printers and choose your printer (click on the grey triangle) you'll see a list of icc-profiles for the printer (SPR1800 standard.icc was marked out as standard profile with a blue dot for the R1800)

Highlight this icc-profile and change by choosing «Another» in the dropdown list so the icc-profile is no longer be marked as standard profile.

That is a problem because "ColorSync" has been automatically selected.  Once "ColorSync" has been force-selected in the "Color Matching" panel, setting "Color Mode" in the "Printer Setting" panel to "Off" does not do what must be done.   It turns off *Epson* color control (since it is an Epson driver, after all), but does not turn off "ColorSync" (which is an OS X control).
