Convert image to GRF format

Question

I have a Zebra Gk420t printer that allows me to make stickers and I need to print an image on them. I read that the images must be in GRF format (pure hex).

Someone knows how can I convert the images to GRF format in Linux? I read about Ztools software on Windows, but nothing interesting on Linux...

Answer 1

Zebra provides a Java API that can convert graphics to GRF. You can use the command line interface to convert images to GRF like so :

java -jar ZSDK_API.jar graphic myImage.jpeg -s myConvertedImage.GRF
