I am having problems with extra blank lines and $0 lines printing.

If you are using the POP and Project Fields, this feature prints one line for the header information from a POP invoice and allocates a line on the stub for each detail line - even if there is no data in that line item. For example, if a POP invoice has three detail lines entered in the scrolling window, four lines will be allocated on the check stub for that invoice: one for the header information and three for the detail information. If there is no data for the fields on the stub, the detail line prints with a zero dollar value. This can result in large spaces between lines on the check stub.
