Label Printer: Printing out blank labels (PC using Firefox)

On the Margins & Header/Footer tab set all the margins to 0 and all the headers/footers to "--blank--". If your labels end up printing out blank then go back into Page Setup and uncheck the "Shrink to fit page width" as that can cause an issue in some situations.  Also, make sure that the label size is correct as they could cause problems as well.
