The default is wrong (you can press ctrl-shift-K and change this)
Convert
them to the working space.

Duh. Or just click Option 2, which still didn't allow adjusting
resolution. This comment suggests that the incomprehensible term
"working space" means "Photoshop's tools for manipulating color."
That's not an issue. These shots require only cropping and histogram
density adjustment.

Ignore the dpi setting - this is an internal number that normally does
not
change the quality of the result.

BTW - you didn't tell us the problem you are seeing with the pics.

The 4x6 test photo I'm using utilizes about 1/3 of the image area. The
dots are plainly discernable with (my) unaided eye at normal viewing
distance. The shot intended for the jersey display will be 8.5x14. The
dots will be huge. Anyone who doesn't recognize 234 dpi as a serious
quality problem doesn't deserve to have Photoshop CS.

These shots are Nikon lens sharp. I can count the stitches on the
baseball in the test photo on the monitor in high resolution with
"working space" enabled. What I see is not what I get. The Alps
printer produces resolution comparable to 1200 dpi.

I'm down to two likely causes:
1. The Nikon camera locked in the 234 dpi resolution at the moment of
exposure, in which case there is no improving it, or
2. The downloaded XP driver --- Alps last driver was for Me --- is
deficient.

This mystery may be solved when I manage to get the Win98SE Alps
produced driver unzipped. I had forgotten how unstable Win98 is. It's
driving me nuts. I hadn't seen a BSOD in years before this. All I need
to do is to get an optical drive recognized.
