In scanning you want to capture all the detail in the image, so in
Vuescan it pays to set the clipping percentages to 0.
Then in Photoshop you can use a curve adjustment to move the black and
white points inward to improve the contrast. If you set image markers
at points you want to be blackest and lightest you can watch in the
info panel until they reach a suitable value.
For inkjet prints I suggest something like 10-20 and 250-252 as the
limits. Making the lower limit darker doesn't put any more ink
on the page but makes all the adjacent tones too dark. Going to 255
usually makes the highlights look somewhat washed out.
