Best guess. The transparency is a mask and the color value for the mask is saved in the file using the background (BG) color. Usually this is white but can be black if that is the BG colour.
Some applications correctly use this value, but others just see it as another colour. This example using two different viewers.
Bottom is correct, top shows the alpha mask.
My advice for printing. Make sure the image is showing a white background. Export as a jpeg (which does not support transparency) Use the jpeg for printing. Remember there is no white ink in your printer, that is the paper colour.
JPGs. I set foreground AND background to white. I used bucket fill to get rid of the checkerboard patter which I find very annoying.
