I am not exactly sure what you are asking, but I will make some guesses with possible solutions.
If you print multiple invoices per report, you can group on the invoice designator, and set the report to start every invoice on a new page. In addition, you can force a new page when the record count goes over 10 rows. There are various ways to do this, but the simplest would be to add a counter that is set/reset at the start of an invoice, and then conditionally force a "new page before" if that counter reaches 11. You can also set this to force a new page for every n + 1 records (the 11th record, the 21st record, the 31st record, etc.)
If you just don't want the report footer to show up, you can either suppress it or issue a "new page before" on report footer. This is handy if you keep a summary page for reference (# of invoices in run, total balances, etc.).
If you just don't want a floating footer, you can select "print at bottom of page" for any section. This is handy for group totals. That, with "Repeat Group Header on Each Page", you can get some very nice looking invoices.
