Digital BW, The Print

Can you see the paint building up on your mask? Option/Alt-click on the
mask in the layer stack to show the mask by itself.

If not, you probably have your painting tool set to a mode that does not
change black and white, ie, screen on white or multiply on black. Check
to make sure you don't have a painting mode turned on.

Also try other brushes. It's possible to set brush options so that
nothing happens under certain circumstances.

Does anything happen when you set foreground to black and paint on a new
white background?

If none of these solve the problem, reset Photoshop's preferences.

Good luck,
