Tutorial format

Every step tells you what to do, then shows the label that comes out. Each step also carries a collapsed Behind the scenes block with the layout as the T3 API receives it. You never need to open it. It is there if you are curious.

Sections explaining why look like this. Skip them if you just want the next step.

Checklist

You will need:

  1. The T3 extension, installed and logged in to Metrc. See installation.
  2. A printer, if you want to print what you build. A thermal printer, a sheet of Avery labels, or plain paper all work.

Neither of these is needed to follow along. The label renders in your browser.

Without a T3+ subscription your labels render with a T3 watermark. Everything in this tutorial still works. See the watermark.

Open the Label Studio

Click the T3 toolbar menu in the bottom right, then Label Studio.

The studio has two panes. The left pane configures the label, the right pane shows the generated PDF. The left pane's tabs each control one part:

  • Template Builder sets what you are printing on.
  • Layout Builder arranges what goes on the label.
  • Label Data supplies the list of records, one per label.
  • Images holds the images your layout can use.

The other tabs are covered in the Label Studio reference.
