There are a handful of core principles involved in the T3 label generator:
-
Labels are 100% customizable: T3 labels are controllable by the user. This includes:
- Label size
- Label content layout
- Label text
- Label text formatting
- Tables
- Barcodes and QR codes
- Label margins and padding
- Print order
- Label orientation
- Data templating
- Labels are compatible with all printers: All types of printers, including inkjet, laser, direct thermal, and thermal transfer, support the PDF format. Once you've generated a label PDF, you can send that PDF directly to your printer, no extra software required.
-
Inserting Metrc data into labels is easy. T3 label layouts use Jinja templates for inserting dynamic content. This means that showing item names for a list of different packages is as easy as using
{{ package.item.name }}
. - T3 labels automatically resize: T3 label layouts automatically adjust based on the size of the label, and the text inside that label.
- Label generation is API-driven: T3 label PDFs are generated via the T3 API. You don't need to know anything about APIs to generate labels, but this also means you don't need to use the T3 extension's label studio to create labels - you can use the API endpoint directly.
- Anyone should be able to make and change labels: T3 resources for label generation are intended to allow users of any ability to create and modify labels. Label generation should be quick and painless.
All the PDFs shown below were generated by T3. Below each screenshot is the actual printable PDF and the source data used to generate the PDF via the T3 API.
