How do I print Datamatrix barcodes on thermal printers?

This document describes the different control codes for various thermal printers to be able to print Datamatrix codes. Of course, the coordinates (horizontal/vertical) ultimately depend on the desired exact position on labels.

In the binaries, you can find the pages from the documentation of the various printers.

It is strongly recommended to print a text that represents the barcode in addition to the Datamatrix barcode. This is similar to the numeric value of a barcode that is often printed below the barcode. Since the total text for a Datamatrix is too long, a compressed variant of the barcode has been created. This is available as the 'TwoDimensionalBarcodeHash' field. This field can be used for searching and comparing on the screen to ensure that the correct barcode is being used, for example when changing a sales price for a specific barcode.
