Who this is for
Teams that already own a Zebra GK420t and keep the data they label in Excel.
How it works
Step by step
- Create or open a label template and place the fields you need — text, barcode, QR, RFID.
- Add your workbook as a data source and pick the sheet and header row.
- Drag a column onto each field, or pick the column from the field's data-source dropdown.
- Preview row by row to confirm the mapping, then print the range or the whole sheet.

Practical notes for this pairing
- At 203 DPI a single printer dot is about 0.125 mm. Size barcodes in whole dots so the narrow bar lands on an exact dot boundary and stays scannable.
- The GK420t prints up to 104 mm wide. Check the widest value your Excel data can produce against that width before running a full batch.
- Connections available on this model: USB, Ethernet (variant-dependent). Pick the one the machine running the job can actually reach.
- LabelInn sends ZPL II straight to the GK420t, so the label your data fills is rendered by the printer itself rather than by an operating-system driver.

Frequently asked questions
Can the Zebra GK420t print labels directly from an Excel file?
Yes. LabelInn reads your Excel data, binds the columns to fields on a label template sized for this printer, and drives the GK420t over the connection you selected. You do not export an intermediate file per run.
Do I need a driver for the Zebra GK420t?
For the direct ZPL II path, no — LabelInn generates the command stream and sends it over the connection you selected.
Print your Zebra GK420t data on the printer you already own
This feature runs on Starter — $7.99/mo, or $79.90/year (pay for 10 months, use 12). Signing up starts a 14-day Pro trial, so you can bind your own Zebra GK420t data and print a real label before you pay anything.
