Skewed Picture files when printed

[KAZJUL]

I have an Excel 2000 file with a veriety of picture formats, .tiff and .wmf, for example, inserted using insert-picture. When I am viewing the pictures in excel everything looks fine, but when I print the file, the pictures get skewed (fore-shorttened in the vert. direction and stretched in the horizontal direction). I have been able to fix this upto this point by simply stretching the picture to offset the print skewing. We now however have a new company Logo design, of which we are not allowed to stretch the image, therefore I am now looking for a better (proper) solution, if one so exists.
