Print Grid using PrintPreview on Windows with Firefox

I have a grid with over 100 records on it. My client used to use the Print Preview function to print out the grid. However he now says that only the first page worth is printed rather than all the pages.

Please can you tell me how I could restore that functionality.

Thanks

Sorry I should have said that the version is 3.0 Pro. Thx.

Can you share a sample or a live demo where the problem can be checked.
