Why doesn't my label print correctly?

There are three situations:

1. The main reason is that your shipping label file size is not 4x6 inches. At this time, you need to set the correct label size. This needs to be set on the shipping platform or online store, depending on your file source. This part will be listed step by step in the How to print labels on the following platforms.
   

   Note: Please make sure that the following three dimensions are consistent for correct printing:

   1. Your document size.
   2. The label paper size you are using.
   3. The size option you selected on the print preview page.

2. The label size is not properly configured when switching to print labels of different sizes. Please select the size that corresponds to your shipping label.

   Please see the settings below. The following is an example of the most common 4x6 inch ship-ping label.
   
   

   For Mac：

   If you print a 4×6 size page. In the print dialogue, please be sure to select your "Paper Size" appropriately (for example 4.00×6.00").

   
   

   In the presets settings, you can permanently save the settings for this printing to avoid repeated settings.
   
   

   For Windows：
   

   Go to the "Settings" -> "Bluetooth & devices" -> "Printers & scanners" -> "Munbyn RW402B" -> "Printer preferences" -> "Page" -> "Paper Name", select the correct size for the printer (please select the 4×6 inch or 102*152mm).
   

    

3. If your file size is correct, only a small part is missing, for example, the barcode is not printed, and the consignee's information is not printed.
   
   First of all, you can check if your adapter is included in the package. You can see a picture of the adapter in section Why does the printer keep beeping? If the adapter is correct, follow the steps to calibrate the paper:
   

   • Load no less than 4 consecutive labels into the printer.
   • Once the cover is closed, the machine will automatically attempt to feed the paper.
   • If it fails to do so, please manually calibrate the paper: press and hold the feeder button until you hear a "beep".
   • The printer will then perform label identification and calibration.
