Print labels from SAP HANA

Who this is for

Plants and warehouses running on SAP whose HANA database can be queried directly and whose labelling is currently a separate manual system.

How it works

1. Install the LabelInn Windows app and your SAP HANA client driver on the machine that will run the job.
2. Add the SAP HANA connection: host, port 30015, database and a database user that can read the tables you need.
3. Write the SAP HANA SQL 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 HANA SQL. Use FETCH FIRST n ROWS ONLY 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 SAP HANA.
• 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 SAP HANA?

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

Which SAP HANA SQL do I write?

Ordinary SAP HANA SQL. LabelInn does not rewrite your SQL; it runs the statement you saved and maps the result columns onto label fields. Use `… FETCH FIRST n ROWS ONLY` while testing.

Can I print to a Zebra or TSC printer from SAP HANA 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.
