Digital BW, The Print

I found the solution:

I load the selection and use the Patch tool in 'Source' mode and drag
the selection a little bit away from the dust. Seems to work extremely
well in most cases. I haven't payed much attention to the patch tool
until now... 

Both with the patch tool and the healing brush tool I find that
sometimes the grain structure is screwed up when I use them. In those
cases the clone stamp with a hard edged brush works better.

In any case, I like to get rid of all the dust, whether it's visible in
the final print size or not. I often go back later and make
enlargements, so it's nice to know it's done once and for all.
