labels will always be printed on a label printer. Meaning, whwenver a price or shelf label is created it needs to be printed on such a printer. Right now this isn´t possible. A pdf file will be created which can be printed on a regular printer. But nobody will stick a DIN A4 sheet on a item or on a shelf, therefore these labels needs to be directly printed on a label printer. Funcitonality needs to be similar to the document routing in WHS. Those license plates will be printed directly on a label printer and the design is a ZPL code.
Right now I don´t see any possibility to actually use the function the way it is right now.
