Single barcode label printing option

There should be option to change barcode label size. Now i can see the is not option to change the barcode size & Also there is such a stupid printing option. We cannot print single label even if we want to print one label it will print 2. I mean who though about this. What will a person like me will do who want specific number of labels to be printed. If want to print one label it will print 2 labels unnecessary wastage of labels.
