Allow to print barcode of a product

I like the idea of a general configuration for representing product barcodes. But IMHO an implementation based on save _eval which could allow all product fields could be more sufficient, as there are

Also as an additional functionality, matching could be user definable, as

But I can’t see a good general implementation for a report for now. Your idea

reminds me too much of the party label report. It was implemented for printing address labels for parties.
But IMHO the using on special labelling paper with self-adhesive stickers (Avery, Zweckform,…) is very limited, because the vertical size of a label is variable and defined by the label text and a waste of resources, as a management for empty labels on a page is missing… Serial label printer with endless stickers are also not supported, as these printers usually work very different (ZPL2, ESC-P, …). So the party labels can be printed on plain paper, cut with scissors and glued manually… but for cutting there are crop marks missing and the result is limited in use… So we don’t use the party label report in any of our projects and deactivate it.

OTOH it would be excellent if Tryton supports the users, to use barcodes in their own custom Product/Party Label reports.
For this it would be very helpful if Tryton provides a field or property with the bar code binary data.
