2.0. Printing Issue

2.1. Label Issue

2.1.1. Why doesn’t my label print correctly?

There are three situations:

The main reason is that the size of your shipping label file is not 4×6 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 platform setup.
It is not set correctly when switching to print labels of different sizes. Please see the settings below.
Please select the size that corresponds to your shipping label. The following is an example of the most common 4×6 inch shipping label.

For Windows:
Go to the “printer preferences” -> “advanced” ->”paper size”, select the correct size for the printer (please select the 4×6 inch or 100*150mm)

For Windows:
If you print a 4×6 size page. In the print dialogue, please be sure to select your “Paper Size” appropriately (for example 4 x 6″)

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

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. The picture of the adapter can be seen in the sixth point. If the adapter is correct, follow the steps to calibrate the paper.

Load no less than 4 consecutive sheets of paper into the printer.

2
After the paper stop moving, press and hold FEED (red/green light), and when you hear a beep, release the feed.

3
The printer will learn the size of the paper at this time. After the process is complete, the printer is back to normal.

2.1.2. Why is my label printing too small If the document size is not in 4*6 inches, or there is a large blank area around the shipping label(may on the right or left), or the label prompts “cut on dotted line”(please refer to the picture).we need to cut off the blank area to print correctly

2.2. Print Quality Issue
2.2.1. Why is the printed label too dark and cannot be scanned?
Try to choose PDF file format for printing instead of PNG, PIG, and other image formats, when the barcode you print out is very fuzzy (please refer to the picture).
If the barcode still cannot be scanned,The reason is that the printer’s density and speed settings are not suitable for the current shipping label, we need to adjust it in the printer settings please try to reduce thedensity and increase the speed (Please refer to 2.2.5 for specific operation steps).
2.2.2. Why is the printed label not clear?
