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 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.

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 toyour shipping label. Below I use the most common 4×6 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 4×6 inch or 100*150mm)

②For 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 x 6).
In the presets settings, you can permanently save the settings for this printing to avoid repeated settings.

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,

① Press 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.

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:

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.

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.

Why does the printer out a lot of blank paper after one successful print? / Why can't I print continuously?

A:①. Please cancel all printing sequences in the computer.
②. Load no less than 4 consecutive sheets of paper into the printer.
③. After the paper is stable, press and hold FEED (red/green light), and when you hear a beep, release the feed

The printer will learn the size of the paper at this time, and the top of the printer will light up in green when it stops. After the process is complete, the printer returns to normal.

Why my labels are not sharp / dark?

A:
Try to choose PDF file format for printing instead of PNG, PIG and other image formats

For Windows:

You can do this by entering:
Settings -> Devices -> Printers and Scanners -> Right-click on ‘Munbyn ITPP941’ -> Manager -> Printing Preferences -> Page Setup -> Density/Speed.

For Mac:

1).Choose printer features

2).Adjust the density, Try to choose low speed while high density

Why are there some white spots in the printed labels?

 

A:
It is likely that the printer head has gotten dirty.

(1)Please turn ITPP941 off and allow it to cool down

(2)Please use the provided alcohol pads to wipe the printer head clean. Any 70% Isopropyl Alcohol pad would work. These are commonly available in pharmacies and grocery stores as well as on Amazon. Image below shows the highlighted areas that could cause this fade / dead zone.

(3)Allow 2-3 minutes for components to dry, then turn ITPP941 back on.

Please try to use high-quality thermal label paper (such as munbyn label paper) to avoid the poor quality label paper coating peeling off and remaining on the print head, resulting in unclear printing.

Q. How to install Windows & Mac Driver?

A: The package contains USB Disk, which contains instructions, driver files and installation videos. You can use it on Windows and Mac OS.

Q. Why i am printing blank labels or printing labels incomplete?

A: (1) The most common reason is that your labels are loaded in upside down. Please ensure your labels are properly loaded. The label that you peel off should be facing the ceiling when it comes out of the printer

(2) Ensure your labels are “Direct Thermal” labels.

(3) If printing a PDF file, perform a print preview before printing and adjust the zoom ratio. And if the PDF document is too large, you can use “Acrobat Reader DC” to crop the document to make the printing effect better.

(4) Place the thermal label paper correctly, then find the green button (FEED key) on the printer surface, press or hold for 3 seconds, and let the printer automatically identify the label paper size.

(5) Change the paper size in the computer printer properties. For example, to print a 4×6 shipping label, please set the paper size to 4×6 inch or 100*150mm in the computer printer-printer preferences.

Q. Why can't I print after installing the driver?

A: This may be because the print port is occupied. Please set it in the printer properties of the computer and change a different USB port.

Specific operation: computer equipment and printer – printer properties – port – select other USB ports (USB001~USB003)

Prints lines in label and not clearly, how to make it right? And how to print a full postage label on the 4x6 labels?

For PDF printing, we recommend Adobe Acrobat Reader DC this software to open and print, remember to set the “Halftone” to “None” if you use other format file. For Mac users, go into the cupsctl web interface and make changes to the printer. Some user suggest changed the color option to “none” and print darkness to “15” and they came out crystal clear.
