How sharp are your prints?

Some of my 4x6 prints produced on a Kodak machine at my local drug store
seemed a tad soft to my eye so I had them print out a test pattern.

The result can be seen here

Both horizontal and vertical resolutions are around 11 lw/mm (5.5
cycles/mm] which translates to about 280 dpi if I understand things
correctly.[1]

Obviously 280 dpi is pretty good resolution, far better than my unaided
eye can resolve. So I'll have to blame my soft shots on shaky hands.

I wonder if anyone else has run any printer tests? I'd love to hear how
my local drugstore compares with other commercial printing services, or
your inkjet.

I got soft prints back from my film SLR with sharp 50mm lens, While a
compact zoom camera was much sharper. I had reprints made that were much
better. This seems to be a problem with all but the pro labs.

I though this would not be an issue with digital but, alas, I was wrong. I
had vacation pictures printed from my digital Rebel. There was a slight
softness. I could not read a sign on the print that was clearly visible in
the image.
