Printing Issue
Label Issue
1. Q: Why is my shipping label not completely printed? Too small or only part of
it?
A:There are two reasons:
1. The main reason is that the size of your shipping label file 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 platform setup.
2. It is not set correctly when switching to print labels of different sizes. Please see the settings below.
You should choose the size corresponding to your shipping label. Below I use the most common 4x6
inch shipping label as an example.
①For Windows: Go to the ‘printer preferences’ -> ‘advanced’ -> ‘paper size’, select the correct
size for the printer(please select the 4x6 inch or 100*150mm)
②For Mac: If you print a 4x6 size page. In the print dialogue, please be sure to select your

8
"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.
2. Q:Why I printed blank labels?
A: (1) The most common reason is that the labels were loaded upside down. Please ensure your labels
are properly loaded, the tearable side up.
(2) Ensure your labels are "Direct Thermal" labels, The paper enclosed in the package meets this
condition
(3) If above are correct, but the printer still print blank labels or the label cannot be completely printed.
Please print the self-test page,
①Press FEED(green/red light) button and hold on;
②Release after you hear two consecutive beeps
The printer will print a self-test page. If the self-check page is not printed, please contact us for return
and exchange.
3. Q: Why is the label stuck in the position where the barcode is printed?
A:Please follow the steps below to set, try to reduce the density and printing speed, choose Dotted
line.
For Windows:

9
You can do this by entering:Settings -> Devices -> Printers and Scanners -> Right-click on 'Munbyn
ITPP941' -> Manager -> Printing Preferences -> Page Setup -> Dotted line->Apply.
If the problem is still not solved, please follow point 6 and reduce the density to 2 and the speed to 4.
(2)For Mac:
Access these settings directly from the print menu as shown below.
If the problem is still not solved, please follow point 6 and reduce the density to 2 and the speed to 4.
