Barcode Labels
v1.0.0Overview
What number goes on the sticker, and how it gets onto paper. A catalogue row is given an EAN-13 or a Code 128 number, the number is checked, and a sheet of labels for that row is drawn as a PDF from the row’s own screen. Both symbologies are drawn inside the add-on, as vector bars — which is what makes a label read on whatever printer and scanner it meets. A thirteen-digit number whose last digit does not match the twelve before it is refused with the right digit named — printed, it would simply never scan — and it is never corrected silently, because the number on your paperwork is yours. Two rows carrying one number is refused too, naming the row that already holds it. The sheet is a real PDF: A4, twenty-four labels, three across and eight down, described by its measurements rather than by anyone’s catalogue number. The numbers live in the add-on’s own settings; your record is read and never written. It does not issue or register numbers — that is a numbering authority’s job — and it reads no scanner. Nothing is fetched and there is no account.
What it attaches to
An add-on extends an app you already run, and is never deployed on its own. This one attaches to:
What connecting lets it do
Switched on, it reads the record whose screen it is drawn on and writes nothing of yours — the numbers it hands out live in its own settings. It reaches nothing outside your installation, and both symbologies are encoded from tables inside the bundle: there is no key to keep and nothing to sign in to.
Addresses its server code may reach
None. It reaches nothing outside your own installation.
What it needs to connect
Nothing to connect
What it adds
Where it appears 2
- Its own panel under Add-ons in the dashboard settings
- The actions on one record’s own page
Tables it brings 0
None — it brings no tables of its own.
Settings you configure 1
- Numbers given to catalogue rows
If you switch it off
Disconnecting removes an add-on’s surfaces. It never drops the tables it created, deletes the files it wrote, or removes the rows it added — everything it wrote stays in your database.
What stays
Your catalogue is untouched — it brought no tables and never wrote a row. The numbers it gave out stay in its own settings, and a sheet you saved is simply a PDF, wherever you put it.
What goes
The label actions leave the record’s page and its panel leaves the add-on settings. Your rows keep their names and their screens, with no button left behind.
About the demo
This one calls no outside service at all — in the demo or self-hosted — so it has no stand-in transport, and there is nothing to switch off. The add-ons that do reach out ship one and it is on by default, so no demo on this site makes a real call to anyone else’s service.
How to switch it on In your own workspace, open Add-ons in the settings and switch Barcode Labels on — from then on a catalogue record’s own page carries the number, its bars and the sheet.
