You can print a label you designed in Microsoft Word on a thermal label printer, but the dependable way is not Word's own print button. Save the Word file as a PDF and open it in the NIIMBOT app, which sizes it to the roll for you. If what you actually have is a list — names, addresses, asset numbers — skip Word altogether and use the app's spreadsheet import. Printing straight from Word works once NIIMBOT's printer driver is installed — on Windows, and now on a Mac too — but only once the page size matches the label. Here is each route, and why the third one goes wrong so often.
The quickest route: save as PDF, print from the app
In Word, use File → Save As → PDF. Open the NIIMBOT app on your phone or computer, start a label at the size of the roll you have loaded, and import the PDF. The app scales the page to the label, so you are not fighting margins or printer settings, and PDF printing works on every NIIMBOT printer in the range.
This is also the right route if the design is already finished — a letterhead logo, a product label someone made in Word years ago. Our guide to making labels look professionally printed covers why a design built for A4 often needs its type enlarged once it lands on a 50mm label.
If it is a list, Word is the wrong tool
Most people reaching for Word are really trying to do a mail merge: forty names, a client list, a set of folder spines. On a label printer that job belongs to the spreadsheet, not the document. Put the list in Excel or Google Sheets, import it in the NIIMBOT app, map the columns to the text boxes on your label and print the run. Our guide to printing labels from Excel walks through it step by step. It is quicker than Word's mail merge and it never misaligns, because every label is laid out on the label itself rather than on a sheet.
Printing straight from Word on Windows
If you want Word's print dialog, the printer has to appear in Windows as a printer. That means a model with a USB connection — the 2-inch B1 Pro and B2 Pro, the K3 desktop printer and others with a USB port — plugged in, with NIIMBOT's Windows driver installed. The pocket models that connect by Bluetooth only, such as the D11 and D110, print from the app rather than from Windows. Our support page has the downloads, and the printer operation guide covers setup.
Then set Word up for the label, not for paper:
- Page size: Layout → Size → More Paper Sizes, and enter the label's own size — 50×30mm, 40×30mm, whatever is on the roll.
- Margins: set them to 1mm or less. Word's defaults are 25mm, which on a 30mm-tall label leaves almost nothing to print on.
- Orientation: match how the label comes out of the printer, which is usually portrait for a narrow roll.
- In the print dialog, choose the NIIMBOT printer and pick the same label size in its printer properties.
Why it comes out shifted, tiny or blank
Almost every failed Word print has the same cause: the document is still A4. Singapore's default is A4, and a guide written for the US will tell you to pick an Avery sheet template such as 5160 — that is a page of labels for an office printer, not a single label on a roll. The driver then shrinks the whole page down to fit the label, so you get a tiny, off-centre print or a blank one. Set the page to the label size first and the problem disappears. If a print is still offset, NIIMBOT's own advice is to bring the layout into its software instead — which is the PDF route above.
Barcodes and QR codes are better made in the app than in Word, where they are usually fonts or pasted images that blur at small sizes — see printing barcodes and QR codes.
On a Mac
NIIMBOT now makes a printer driver for macOS as well, so a Mac can print from Word the same way a Windows PC does: install the Mac driver from the downloads on our support page, set the page to the label size exactly as above, and choose the NIIMBOT printer in the print dialog. The Mac driver covers the B1, B31, B4, B1 Pro, B2 Pro, B21 Pro, M2, M3 and K3 — our Mac driver guide has the full model table and setup steps.
On any other model, use the PDF route. NIIMBOT also has desktop software for macOS if you would rather design on the computer than on your phone; it supports most of the B series and the thermal transfer printers, though not the B2, the H1S or the pocket D-series.
Which printer, if you mostly work from a PC
For office and document filing work done from a desk, a USB-connected 2-inch model or the K3 is the comfortable fit, on Windows or a Mac. The PDF and spreadsheet routes work on every model in the range, and plain white labels cover most office jobs. Every printer ships from our Singapore warehouse with a 1-year local warranty.
