Well, I'm not Fred but...
This was covered in the 2023.100 thread but I'll repeat it here. The R800 is now 20 years old and those old Epson drivers had two areas where you could select something they called "Quality". Newer drivers do not have these contradictions. You are looking at the main driver window where it shows "Quality
Options". These are basically presets where you can select an option and the driver automatically selects several parameters. Qimage has in fact set quality to the highest available for that paper type but the driver doesn't know how to select the "preset" properly. There isn't even a "Draft" quality for Photo Quality Inkjet Paper (see below).
If you want to see the actual quality setting in the R800 driver, click the "Advanced" button on the bottom right of the first driver window and then click "Continue" if you get a warning message about you having to be an expert to use that mode. On the advanced window that appears, you'll notice that there is a new quality dropdown that says "Photo". In fact, "Photo" is the only available option for Photo Quality Inkjet Paper: there isn't even a selection for "Draft". So Qimage actually made the proper setting but the driver didn't know how to update the selection on that other screen.
P.S. 2023.100 says it chose "Fine" because Epson changed their wording back in about 2005 but only the names changed so Qimage is still doing it right (setting it to the highest available which the driver calls "Photo") but naming convention for the quality setting might not line up if you happen to still have a printer that is that old... and is still running.
