Printer setup

Tool Tag Printer prints from your browser through a small helper program from your printer's maker. Install it once on each computer that has a label printer connected. Use Chrome or Edge.

DYMO LabelWriter

1. Install DYMO Connect for Desktop from dymo.com (Support → Software). Make sure it's running — it sits in the system tray.
2. Plug in the LabelWriter and load your label roll.
3. Open this link once. If the browser warns about the certificate, choose Advanced → Proceed. This lets the browser talk to DYMO on your own computer.
4. In the app, set Printer to DYMO, press ↻, and pick your printer and label stock.
5. If your browser asks to allow access to devices on your local network, choose Allow.

Zebra desktop printers (ZD410, ZD420, ZD421, GK420d, etc.)

1. Install the Zebra printer driver and Zebra Browser Print (free, from zebra.com → Support → Software).
2. Start Browser Print. Open this link once and accept the certificate warning.
3. In the app, set Printer to Zebra and press ↻. Browser Print will ask whether to allow this website — click Yes.
4. Pick the label size that matches your roll, and set the DPI to match your printer (most desktop Zebras are 203 dpi; "-300" models are 300 dpi).
5. If the first tag prints offset, run the printer's media calibration (hold the feed button until it flashes twice).

Still not printing?

• The status light in the app header should be green. If it's red, the helper isn't running or the certificate step above was skipped.
• Close and reopen the DYMO or Zebra helper, then press ↻.
• Use Save PNG to print through any other label software as a fallback.
