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)
