Custom Page break in crystal Reports c# Windows Application

In my C# .Net windows application I have to implement an Invoice, bill, report for a hotel management system. My issue here is that I don't know how to put page breaks in crystal report depending upon the number of items in the data source. Now am using "New page after " formula as below

    If​Remainder (RecordNumber, 5) = 0 then true else false

And​ it's ​working fine.. Now​ in my printer am using the Roll​Paper​ to print​ the invoice. And​ Here , if the table consists​ of 3 items, the printer will take a whole paper​(if the paper is A4).I need the printer to stop printing depending upon the number of items in the data source So we can avoid wastage of paper.. hHow​can I​ solve this?
