We have Android application which prints receipts as images. We use calling ZebraPrinter.printImage() method from interface GraphicsUtil.
On older Zebra RW420 there is no problem (except for slow print), but same code doesn't work on new ZQ520. It prints a lot of hexadecimal characters.
Same issue is when I print image from Zebra's Android application Zebra Utilities. Firmware version of our ZQ520 is V76.19.10Z.
Does anybody know where the problem is?
Thanks for your replies.
