One solution to the problem of printing partial lines is to evaluate, below the cell performing the lengthy computation, the following:

Dynamic[partialString]

and then update the definition of partialString in the course of the lengthy computation, as below:

Do[
 partialString == "";
 Pause[0.25];
 partialString == "First part...";
 Pause[0.25];
 partialString == partialString <> "second part...";
 Pause[0.25];
 partialString == partialString <> "final part: " <> ToString[i];
 Pause[0.25];
 Print[partialString], {i, 1, 5}
 ]

Hardly elegant, but it works.
