It might improve quality if you have some kind of printing mechanism
that upscales by pixel replication or something.  Then upscaling in
GIMP with bicubic interpolation might very well improve the quality
of the resulting image.  Agreed you cannot add useful information - but
having a fuzzy image is generally better than having a pixellated image.
