bug fix for osCommerce contribution

need a bug fix for an osCommerce contribution called "Batch Print Center" (see link below) [login to view URL],2720/category,all/search,batch+print This contribution makes it possible to print labels for orders. I can select date from and date to and also certain order status to print labels on pdf. Problem is that if more orders are selected than labels fit on one page the script produces only the first page with labels and beginning with the second page gives out just empty pages. Who can fix this bug for me?
