You can print your own parcel and address labels at home in Singapore with a direct thermal label printer that takes 100×150mm (4×6") stock — no ink, no toner, no trip to a print shop. For marketplace orders you switch your seller centre to thermal printing so it hands you an A6 airway bill instead of an A4 sheet, then print it straight from your phone or laptop. For everything else — a Carousell handover, a gift, a return address — you type the address into the app and print it on a smaller label. Here is the whole process.
One size covers Singapore: 100×150mm
Shopee, Lazada and TikTok Shop all issue airway bills at 100×150mm, and the local couriers you hand parcels to — SingPost, Ninja Van and the rest — use the same size. That means the printer has to accept a 110mm-wide roll. In our range only the NIIMBOT B4 does: it supports 20–110mm label widths (108mm effective print width) and prints the courier size directly. A 3-inch machine like the B31 stops at 75mm, which is fine for product and shelf labels but will never fit an airway bill.
The stock itself is the 100×150mm white label, and the rest of the sizes that fit the machine sit in the B4 Labels collection.
Turn on thermal printing in your seller centre first
This is the step most people miss. By default the marketplaces give you an A4 PDF with the waybill printed in one corner, which is useless on a label printer. In Shopee Seller Centre the setting lives under Shipment → Shipping Setting, where you enable the thermal printing toggle; Lazada and TikTok Shop have the same option under their shipping or printing settings. Once it is on, the downloaded file is a 100×150mm page that maps one-to-one onto the label.
Then it is: download the waybill, open it on your phone or computer, and print to the B4. If you have not paired the printer yet, our guide to connecting a NIIMBOT printer to your phone covers iPhone and Android.
Print the whole batch, not one label at a time
Ten orders is fine label by label. Fifty is not. Every NIIMBOT printer works with the NIIMBOT app, and the app imports a spreadsheet and prints the rows as a batch — it is an app feature, so the whole range supports it. That is the difference between an hour of packing and an evening of it, and our Excel batch printing guide walks through the column mapping. If you are gearing up for a sale period, the 11.11 and 12.12 prep checklist has the rest.
Address labels are a different job from airway bills
Not every parcel comes with a waybill. A Carousell meet-up you decide to post instead, a birthday present going to a cousin in Punggol, a small business writing its return address forty times a week — for those you type the address into the app, pick a font size and print. A 2-inch machine such as the B1 Pro handles 20–50mm stock, which suits a return address or sender sticker; for a full recipient address, 40×60mm or 40×80mm is a comfortable minimum. Plain white labels are the cheapest way to do it, and the refills list every size we stock.
Why thermal rather than an inkjet
There is no cartridge anywhere in the range — the print head burns the image into the label, so the only running cost is the paper. At S$7.90 for a 460-piece roll that is well under two cents a label, and nothing dries out between busy weeks.
The one honest caveat: direct thermal labels darken in sustained heat or direct sun, which does not matter for a parcel that gets delivered this week but does matter for something stored outdoors for a year. If you need permanent, use a thermal transfer printer, which prints ribbon onto PET and resists fading, water and oil — the difference is explained in do NIIMBOT labels fade over time.
Every printer ships from our Singapore warehouse with a 1-year local warranty.
