I want to know how I can convert to ZPL from image.
There is SDK function PrinterUtil.convertGraphic() on JAVA, Android SDK.
However I can't find it in iOS SDK.
Is there other function or options If it doesn't support from iOS ? (not store image)
This is because I can't use printer buffer since storeimage() slower than write(), the image placed next label.
I have to check one by one before next label data.
