Footer image cropping

Hi

I'm experiencing issues when adding png images into footers.  When I add the images into the footer, the bottom and right of each image is cropped when printed, no matter the size of the image.  The print preview of the images looks correct.

There is an additional oddity to this as follows - if I add a copy of one of the images into a cell in the main boy of the doc, then print the doc, all of the images print correctly.

Any advice would be great.
