Node that can be used to produce barcode graphics. It is a wrapper around the jsbarcode library found here https://github.com/lindell/JsBarcode.
You have to input the barcode content at msg.payload and optionally the type of
barcode at msg.type. The default barcode type is CODE128. The output svg is
available at msg.payload for further processing. You can e.g. insert it into
a pdf with the node-red-contrib-pdfmake node.
Use http://www.columbia.edu/~em36/pdftoprinter.html to print pdf directly to standard printer.
You can create programmatically pdf documents in a node-red flor
with help of the node-red library node-red-contrib-pdfmake.
Displaying on a dashboard can work with node-red-contrib-ui-svg.
