Force New Page While Printing A List?

I have a requirement to print a number of records from a database. Each record refers to a second database that holds x number of related records. Just like and invoice header and line items.

I first print the report heading on the first page Something like "Invoice list for May 2012"

I then print the Invoice record headings under the the report heading Something like "Inv# Cust # Cust Phone Address 1 Address2 etc"

I then print that data from the original recordset Something like 1234 DR127 555 555-1212 Somewhereville 245th street

I then print the Line item headings Something like "Ln# Item# Description Qty Cost Selling Extn"

NOW Here is my problem: I never know how many line items there will be so can not predetermine when I will need a new page. I do have a way of telling when I am at the bottom of a page by using the text height and incrementing a value for each line

BUT I cannot figure out how to break out of the line item loop, start a bew page then carry on where I left off.

Once all the line items have been printed I need to start the next invoice by printing the Invoice record headings again followed by the header data followed by the line item headers followed by the line items for that invoice.

I have said that the page break may come while in the line item loop but it actually cold come anywhere in the overall loop.
