Exporting an Image

When exporting an image for printing in Lightroom Web, I used to click on the Download icon and it gave me the option to customise my image (size, DPI etc) before exporting. This has now disappeared and I only have JPG size download options. This means I can't edit an image for printing. I have explained this on calls 3 times to customer support, but they only say leave it with us and we call you back. They never do. 

Any suggestions?
