Something like this happened to me also. I "solved" it by discovering that exporting as a bitmap passes through a page where you have to specify the dimensions of the bitmap in pixels. For some unfathomable reason, the default was "ten" (meaning ten by ten pixels) which explained to me after a couple of puzzling outputs from my printer that I was cramming my entire drawing into a rather too small little square, of 100 pixels in area. After expanding to 1000 by 1000 pixels, the saved bitmap could be opened into the gimp with a rather better appearance.

Another pitfall is forgetting to widen the drawing's lines, because at the original widths they are invisible in the output of a good printer. I made mine something like half a millimeter wide, opened the bitmap in the gimp, added some blur, reduced the brightness and increased the contrast drastically and got a printout that was decent;y readable. It also helped to increase the printing density.
