Print labels straight from MySQL or MariaDB

Who this is for

Teams running a self-hosted shop, WMS or internal tool on MySQL/MariaDB who currently export a file before every label run.

How it works

1. Install the LabelInn Windows app and your MySQL / MariaDB client driver on the machine that will run the job.
2. Add the MySQL / MariaDB connection: host, port 3306, database and a database user that can read the tables you need.
3. Write the MySQL query that returns exactly the rows you want to label, one row per label.
4. Map each result column onto a label field — text, barcode, QR or RFID — then preview a few rows.
5. Print the result set, or save the query so the next run is one click.

Write ordinary MySQL. Append LIMIT n while you are testing so a preview never pulls the whole table.

What you can do

• Result columns bind to any label field, so barcode and QR content comes straight out of MySQL / MariaDB.
• Re-run the saved query whenever you need the current rows — no export, no copy-paste, no stale file.
• Mix database columns with static text, counters, dates and serial numbers on one label.
• Printed rows are recorded in the print history, so a reprint or an audit can find the exact job later.
• Queries can be parameterised, so an operator supplies a work order or batch number instead of editing SQL.

Questions

Does label data leave my network when I print from MySQL / MariaDB?

The query runs from the machine you installed LabelInn on, against your own MySQL / MariaDB server. Credentials stay local. What leaves the machine is what you choose to sync — the label design and the print record.

Which MySQL do I write?

Ordinary MySQL. LabelInn does not rewrite your SQL; it runs the statement you saved and maps the result columns onto label fields. Use `… LIMIT n` while testing.

Can I print to a Zebra or TSC printer from MySQL / MariaDB without a driver?

For models LabelInn drives natively over ZPL, TSPL or TPCL, yes — the command stream is generated and sent directly. That is independent of the database driver, which is only used to read your rows.
