MODERN OUT review for Retail Barcode Labels

The bar codes really help me organize my inventory. But when I print multiple out at a time, 3 or 4 of them will not print correctly on the Dymo sticker leaving me to try and printing them again. So I cannot print more than 5 at a time otherwise it will mess up and skip and not print correctly. Yes I have the right stickers and set up sizes. If I print less than 5 at a time they come out perfect each time.
