Built for the people who print, not just the people who design

Designer

Real barcode previews

Code 128, EAN, QR, DataMatrix and more, rendered exactly as the printer will emit them — drag, snap, align, undo/redo, version history on every save.

Printing

Honeywell and Zebra, natively

Generates Fingerprint and ZPL from the same design. A tiny print bridge forwards jobs over your LAN — saved printers per team, no retyping IPs.

Print Queue

Jobs wait until someone's at the printer

Jobs queue up with a live preview of the exact label; a person confirms the printer and media, then releases. Cancel, restore, and reprint with reasons — all audited.

Integrations

A JSON API your ERP already speaks

One POST with your data queues a label job — tags fill the design automatically. Supplier keys route jobs from one system to many supplier companies.

Data

Tags & CSV batch printing

Design with {tags}, preview with example data, and print one label per spreadsheet row — with a Qty column for per-row copies.

Team

Roles that match the floor

Owners run the team, Admins design, Managers set up printers, Users just print from the queue. Invite by email; every change is attributed.

Compatibility

Fingerprint in, Fingerprint out

Import existing Fingerprint label code and keep editing it visually. Export back to code or .xld files whenever you need to.

That's the short version — the full list covers the queue, API, partners and more.
