The page breaks on the batch customer statement do not work in Firefox. The batch statements will print properly from Internet Explorer. If using Internet Explorer 10 (and maybe 9), you will need to check 'Compatibility View' under the Tools menu. You will not see the page breaks until you are in 'Print Preview.'
If you have trouble figuring out how to set compatibility view, see the following article: http://support.timesync.com/entries/23364116-How-to-configure-IE-9-IE-10
