This is the guidance I go by, which I picked up from this site.
I have just done the same thing as you.
First, do you care about how large the photo is on a computer screen? I generally target 1024px at the largest dimension.
Second, what is the typical print size she will print at? I can't imagine she will print EVERY photo at 8x12. Most common is 4x6. So, lets assume 4x6, with an option for 8x12.
Target dpi: 171
Largest output dimension 1024 px @ 6 in (this equals 171 dpi).
150-199 dpi gives decent prints.
Now, if you set that, a printout at 8x12 will be 86 dpi, which is probably ok for most people, especially when viewed at a distance.
That will maximize both the onscreen size and print quality.
If you don't care about the size on the screen, use the following:
Target dpi: 200
Largest output dimension 2400 px @ 12 in (this equals 200 dpi).
200+ dpi gives excellent photos.
The resulting 4x6 print will be 400 dpi.
Just my thoughts. I'm interested in whether others agree or disagree with this, but I have had good luck here.
The alternative is to find which few she plans to print at 8x12 and upscale those.
