Support DMRE Datamatrix Rectangular Extension

I suggest to implement the following feature:

Support DMRE Datamatrix Rectangular Extension

A typical use case might be:

LL currently supports only six rectangular Datamaxtrix formats. DMRE are the same as normal Datamatrix barcodes, DMRE just describes some more rectangular formats. DMRE enables printing barcodes for smaller devices, like medical devices. Because of EU2017/745 regulations all medical devices have to have a unique device idenitifer (UDI).

Further Information:

Hi! I wanted to bring this topic back to your attention. More and more barcode scanners are able to work with “Datamatrix Rectangular Extension”-DMRE-codes. So it would be great to be able to print them with L&L.

You can even promote L&L on the e-d-c.info DMRE page, if implemented. See the entry of NiceLabel.

Hi!

Just wanted to ask for ISO/IEC 21471:2025 / DMRE support? Is it already here?

Yes - the DataMatrix supports these DMRE formats:

This also works for LLCP.

Thank you for the confirmation.

I have checked the DataMatrix configuration dialog in the current List & Label 31 version with Service Pack 2 installed.

In the “Format” dropdown, the list ends after the following rectangular DataMatrix formats:

  • 8x18

  • 8x32

  • 12x26

  • 12x36

  • 16x36

  • 16x48

After 16x48, the list is finished. Same as in your sample screenshot.

As far as I understand the standard, these are the legacy rectangular DataMatrix formats from ISO/IEC 16022, not the newer ISO/IEC 21471:2025 Data Matrix Rectangular Extension (DMRE) formats.

The ISO/IEC 21471:2025 DMRE formats should include, for example:

  • 8x48

  • 8x64

  • 8x80

  • 8x96

  • 8x120

  • 8x144

  • 12x64

  • 12x88

  • 16x64

  • 20x36

  • 20x44

  • 20x64

  • 22x48

  • 24x48

  • 24x64

  • 26x40

  • 26x48

  • 26x64

None of these DMRE-specific formats seem to be available in the DataMatrix configuration dialog.

Could you please clarify the following?

  1. In which exact List & Label version and service pack is ISO/IEC 21471:2025 / DMRE support available?

  2. Should the DMRE formats be visible in the DataMatrix configuration dialog?

  3. If they are not exposed in the UI, how can they be selected programmatically?

  4. Are there documented constants or PreferredFormat values for the DMRE sizes?

  5. Is there a manual page, service pack readme, or product sheet that explicitly documents ISO/IEC 21471:2025 / DMRE support?

At the moment, the visible UI only seems to confirm support for the classic rectangular DataMatrix formats, but not for the new DMRE sizes defined by ISO/IEC 21471:2025.

You’re right, DMRE needs additional formats that are not yet available. Leaving open for voting.
