The angle on this image is just a little off so I have to talk about a few things. Black spots on fruit and some on the leaves is more like pear scab. Bartlet is not that susceptible but we see it often. You can read about it here:

But the image shows the spots almost in rows which is more like rust mite damage so have a look here and see if it matches:

In any case have a look here for control tactics in the home orchard:

Thanks Jay!
I believe this is the pear scab. When I look at the leaves/pears it looks like what the article you linked to shows.

Thanks again for the response!
