I got a bunch of photos that are only 560x700 or so and when I print
them on 8 x 11 the features are not very fine. How can I improve on
it?

560x700 pixel is not much information to print at the size 8 x11 inch
and the data must be upsampled. Normally the printer driver does this.
This is convenient, but you cannot control the result.
There are differnt methods to upsample or interpolate. They differ in
speed and quality. Pixel replication is a verry fast method, but the
results are poor. Normally bicubic interpolation is a good trade off
between speed and quality. But there are better methods availably.
Some are implemented as photoshop plugins, others are standalone.
The tool I use for printing is Qimage. It can be use free for 30 days.
so you can find out whether you like the results.

But of cause there are other products in that market.
