You could try this (for the barcode):

Create Barcode from Text (using MyFonts extension)

A quick one. Using Anke's MyFonts extension, and a couple of open source barcode fonts, it is possible to generate a barcode: [image] [image] BarcodeFont.aia (19.4 KB) Credits @Anke for Myfonts extension @ LibreBarcode BONUS BLOCKS (draggable) with random product code generator [blocksbarcodebonus]

The rest should be straightforward text layout...

Thanks Timai2, my intention is to create the label in fields of a layout, then convert it to pdf and print via Bluetooth to a portable thermal printer, all this receiving only a csv file (as an example). all this to be able to print on android versions greater than 10... greetings!
