Printing dithering image through Zebra designer

Hi

I have developed an application using PHP and Javascript. I need to print a dithered image of a person using the zebra gc420t printer. I have a Zebra Designer 2 Software where in the printer settings I can the image to dithering smooth(as shown below).

Now If I add the colored image to the printer and print the label.

Does the printer prints the dithering image?

(P.S: Right now I don't have the printer it was given for service)

And I want to embed this Zebra Designer application to my application so it runs on background and prints the labels. Is it possible?
