A NIIMBOT label maker is a Bluetooth, app-driven thermal printer, and the model you should pick comes down to label width before anything else. The NIIMBOT D11-H and D110-M are compact organizers built for 8–15 mm labels, the B21 prints 20–50 mm product, price and barcode labels, and none of the three can output a standard 4×6 carrier label. If your goal is a Bluetooth printer for shipping labels, you are looking at the wrong end of the range.
The second deciding factor is resolution, and it is where most NIIMBOT comparisons go wrong. The current D11-H is a 300 dpi machine while the D110-M is 203 dpi on identical narrow media. The original D11, still common in secondhand listings and older reviews, is also 203 dpi. Two units sold under the name "D11" do not print at the same level of detail, and neither does the B21 compared with the B21 Pro.
The third factor is the consumable system. NIIMBOT media is grouped into model-specific families and, on current hardware, recognised electronically rather than merely matched by width. A cheap printer becomes an expensive one if the exact refill family is thin on the ground where you live.
D11 vs D110 vs B21: The Direct Comparison
These three cover the searches that bring most buyers to the brand, and they sit in two different categories. The D11 and D110 print on a tiny format for jars, cables, bins and stationery. The B21 prints on a format wide enough for retail price stickers, small packaging labels and larger barcodes.
| NIIMBOT D11-H | NIIMBOT D110-M | NIIMBOT B21 | |
|---|---|---|---|
| Intended use | Fine-text organization labels | Everyday organization labels | Retail, product and barcode labels |
| Technology | Direct thermal | Direct thermal | Direct thermal |
| Resolution | 300 dpi | 203 dpi | 203 dpi |
| Label width | ~8–15 mm | ~8–15 mm | ~20–50 mm |
| Typical maximum speed | ~40 mm/s | ~40 mm/s | ~60 mm/s |
| Mobile connectivity | Bluetooth (NIIMBOT app) | Bluetooth (NIIMBOT app) | Bluetooth (NIIMBOT app) |
| Official desktop printing | Not listed | Not listed | Listed |
| Nominal battery | 1,500 mAh | ~1,500 mAh | ~1,500 mAh on newer versions |
| Main limitation | Very narrow media | 203 dpi on narrow media | 203 dpi graphics and photos |
| Best fit | Small detailed labels | Simple, inexpensive labels | Product labels and larger codes |
Those figures describe current versions where they can be identified. Older D11 and D110 hardware differs, and maximum media width is never the same measurement as usable printable width.
NIIMBOT's Approach: App-First and Model-Specific Consumables
NIIMBOT organises its range by label width and print technology rather than by price tier, and the whole catalogue rests on two structural choices.
The first is app dependence. The printers are designed around the NIIMBOT mobile app for iOS and Android, and only some models also appear on the manufacturer's published desktop software compatibility list. A Bluetooth radio does not make a device behave like a system printer, and a USB-C port used for charging does not guarantee USB data printing.
The second is consumable grouping. NIIMBOT refills are split into separate families on the manufacturer's own store: D-series rolls for D11, D110 and D101; a shared 50 × 30 mm group for B21, B1 and B3S; a Pro group for B21 Pro, B1 Pro and B2 Pro; dedicated stock for B4, N1, M2, M3 and K3. The existence of separate official shopping categories is the clearest evidence that these rolls are not universally interchangeable.
The D-Series: Compact Organizers
Every D-series model is direct thermal, Bluetooth-only, and limited to narrow die-cut rolls. None of them appears on the official macOS desktop compatibility list, so a phone or tablet is the working interface.
| Model | Resolution | Media width | Speed | Battery | Charging |
|---|---|---|---|---|---|
| D11-H (upgraded) | 300 dpi | ~8–15 mm | ~40 mm/s | 1,500 mAh | USB-C |
| D11 (original) | 203 dpi | ~8–15 mm | Revision-dependent | Smaller, older connector | Older connector |
| D110-M | 203 dpi | ~8–15 mm | Up to 40 mm/s | ~1,500 mAh | USB-C |
| D101 | 203 dpi | ~8–25 mm | ~40 mm/s | 1,500 mAh | USB-C |
| H1S | 203 dpi | ~8–15 mm | Up to 40 mm/s | ~1,000 mAh | USB-C |
NIIMBOT D11-H (Upgraded Version)
The unit currently sold as the D11 Upgraded Version carries the hardware identifier D11-H. It prints at 300 dpi, roughly a 0.085 mm dot pitch, which is the reason small text and miniature QR codes stay legible on a format this narrow. Common stock is 12 × 40 mm and 14 × 30 mm, and the media line includes coloured-background, transparent and decorative rolls.
Speed is around 40 mm/s, the battery is nominally 1,500 mAh with USB-C charging, and labels separate at a manual tear bar. The media recognition system identifies NIIMBOT rolls; third-party compatibility is not officially guaranteed. The 300 dpi head sharpens detail but does not widen the format, so the D11-H cannot become a retail or shipping printer.

NIIMBOT D11 (Original 203-dpi Generation)
The first-generation D11 prints at 203 dpi on the same 8–15 mm format. Historical specifications describe a smaller battery and an older charging connector than the current D11-H, and speed and charging hardware vary by revision. It now lives in new-old-stock and used listings, so verify the exact revision before buying.
If you are buying a D11 secondhand, read the resolution printed on the box or the unit rather than trusting the model name.

NIIMBOT D110-M
The D110 is the straightforward everyday option: 203 dpi, 8–15 mm, up to 40 mm/s, around 1,500 mAh and USB-C charging on the current revision, with a body weighing about 149 g. Specified newer versions add automatic paper rewind. It shares the D-series roll family with the D11 and D101, and it is absent from the official desktop software list.
Choose it over the D11-H when fine detail does not matter and you want the lower-cost path into the same media.
Check the NIIMBOT D110 on Amazon
NIIMBOT D101
The D101 keeps the 203 dpi head and 40 mm/s speed but stretches the media range to roughly 8–25 mm, which makes it the step up for buyers who find D11 labels too narrow yet do not need 50 mm product stickers. It uses a 1,500 mAh battery and weighs about 340 g.
The trap here is roll compatibility in one direction only. A roll labelled "compatible with D101" may be too wide for a D11 or D110, so check the roll's compatible-model list rather than assuming the D-series label covers everything.

NIIMBOT H1S
The H1S is the narrow-model outlier because it supports both die-cut and continuous label stock, with manual cutting to a chosen length where the workflow allows. It prints at 203 dpi up to about 40 mm/s, carries a roughly 1,000 mAh battery, charges over USB-C and weighs about 166 g. It is not listed among the desktop-compatible models.
A global-catalogue sibling, the H1, is listed by the manufacturer but lacks a public model-specific specification sheet, so it should not be recommended on the strength of the H1S alone.

The B-Series: Wider Direct-Thermal Printers
The B-series moves up to a 20–50 mm format for price stickers, shelf tags, product labels and the larger barcodes that come with them. Several B-series models do appear on NIIMBOT's desktop compatibility documentation, which is a meaningful difference from the D-series. The wider B3S, B31 and B4 go further, to 75 mm and then 110 mm.
| Model | Resolution | Media width | Speed | Battery | Desktop support |
|---|---|---|---|---|---|
| B1 | 203 dpi | 20–50 mm | ~50 mm/s | ~1,500 mAh | Listed |
| B1 Pro | 300 dpi | 20–50 mm | ~50 mm/s | ~1,500 mAh | Listed |
| B2 | 203 dpi | 20–50 mm | ~50 mm/s | ~1,500 mAh | Model-specific, must be checked |
| B2 Pro | 300 dpi | 20–50 mm (48 mm print width) | ~50 mm/s | ~1,500 mAh | Model-specific, must be checked |
| B21 | 203 dpi | 20–50 mm | ~60 mm/s | ~1,500 mAh | Listed |
| B21 Pro | 300 dpi | 20–50 mm | ~50–60 mm/s | ~1,500 mAh | Listed |
| B3S | 203 dpi | 20–75 mm | Revision/source-dependent | 2,200 mAh | Listed |
| B31 | 203 dpi | 20–75 mm | ~80 mm/s | ~1,500 mAh | Listed |
| B4 | 203 dpi | 20–110 mm | ~80 mm/s | ~2,000 mAh | Must be checked |
NIIMBOT B21 (Original Retro Model)
The retro, camera-shaped B21 is a 203 dpi direct-thermal printer covering roughly 20–50 mm media, with typical formats including 30 × 40, 40 × 30, 50 × 30, 50 × 50 and 50 × 70 mm. The US-facing listing quotes around 60 mm/s, though that figure moves with the version. The battery is about 1,500 mAh on newer hardware, and NIIMBOT lists the B21 among its desktop-supported models.
It remains on sale rather than being replaced by the B21 Pro. At 203 dpi, ordinary stickers and text print cleanly, but photographs and fine graphics look coarse. The B21, B1 and B3S share the widest OEM consumable category in the range, which keeps refills accessible.

NIIMBOT B21 Pro
The B21 Pro is the same 20–50 mm format at 300 dpi, which is the whole point: small monochrome illustrations, fine logos and small text hold their edges where the original B21 pixelates. Speed figures conflict between channels, quoted at roughly 50 mm/s on one regional sheet and 60 mm/s on a US-facing listing, so treat the number as revision-dependent. The battery is about 1,500 mAh and the unit weighs around 321 g.
Two cautions. It belongs to the B21 Pro, B1 Pro and B2 Pro consumable group, so original B21 rolls should not be assumed identical. And the "two-colour" claims apply only to compatible specialty thermal stock, not to full-colour ink printing.

NIIMBOT B1 and B1 Pro
The B1 is the affordable route into 50 mm media: 203 dpi, 20–50 mm, about 50 mm/s, a 1,500 mAh battery and roughly 293 g. It appears on the official desktop software list. Where the D-series exists for bins and cables, the B1 exists for retail price stickers and small packaging labels.
The B1 Pro raises the head to 300 dpi at the same width and speed, with a slightly heavier body at about 355 g. It uses the Pro B-series media group rather than the original B1 rolls, so the consumable side changes along with the resolution.

NIIMBOT B2 and B2 Pro
The B2 is a conventional 203 dpi, 20–50 mm business label maker at about 50 mm/s with a 1,500 mAh battery. Its desktop support is less clearly documented than the B1's or B21's, so verify the driver against your operating system before assuming a wired workflow.
The B2 Pro moves to 300 dpi with a published effective print width of about 48 mm, a 1,500 mAh battery and a body around 348 g. It advertises onboard, offline template printing, which addresses the common worry that a phone must drive every job. That feature is model-specific and should not be assumed on other NIIMBOT printers.

NIIMBOT B3S and B31
These are separate product codes with different specifications, not two names for one machine. The B3S is a 203 dpi unit covering 20–75 mm media with die-cut and continuous stock, a 2,200 mAh battery and a weight around 700 g. The B31 also covers 20–75 mm at 203 dpi but runs to roughly 80 mm/s, weighs about 451 g, and is quoted with a 1,500 mAh battery in one regional specification even though reseller figures differ.
Neither reaches standard carrier-label width. The B3S is a warehouse and retail shelf printer, and NIIMBOT documents a specific transparent-label recognition procedure for it, which tells you media detection is a real setup step on the wider stock.

NIIMBOT B4
The B4 is the model that answers the shipping-label question for the brand. It is a 203 dpi direct-thermal printer covering roughly 20–110 mm, with usable print width quoted near 108 mm in some regional specifications, and it accepts thermal stock up to approximately 100 × 150 mm. Speed is about 80 mm/s, the battery is roughly 2,000 mAh, and it weighs about 757 g.
Media width is necessary but not sufficient for carrier labels. A B4 job still depends on generating a correctly sized PDF and printing at actual size, the same discipline that governs any 4×6 label printer. Sellers moving real parcel volume typically keep the B4 for product and inventory work and run carriers on a purpose-built 4×6 machine.

Thermal-Transfer Models: N1, M2-H and M3
Direct thermal stock darkens with heat, light, handling and chemicals over time, which is fine for organisation labels and shipping labels that live for days or weeks. When a label must survive years on an asset, or sit in a warm or sunlit environment, NIIMBOT switches technology. Its thermal-transfer models use a ribbon, so the print is more resistant to abrasion and exposure. This is the same distinction that separates the two technologies across thermal-transfer printer ranges.
| Model | Resolution | Media width | Speed | Battery | Weight |
|---|---|---|---|---|---|
| N1 | 203 dpi | ~8–15 mm | ~40 mm/s | ~1,200 mAh | ~308 g |
| M2-H | 300 dpi | ~20–50 mm | ~40 mm/s | ~2,000 mAh | ~764 g |
| M3 | 300 dpi | Up to ~75 mm (72 mm print width) | Up to ~50 mm/s | ~2,000 mAh | ~1,170 g |
The N1 is a narrow 203 dpi printer on 8–15 mm ribbon-based cartridges, suited to small labels that need better print stability than ordinary direct thermal. The M2-H is the 300 dpi workhorse for durable business, asset and product labels at 20–50 mm. The M3 tops the group with 300 dpi, media up to about 75 mm, an effective print width near 72 mm, and label lengths from roughly 8 mm to 350 mm.
Two practical notes. N1 ribbons and cartridges are a separate ecosystem from M2 and M3 supplies. And "colour" on these machines means single-colour or specialty output that depends on the installed ribbon, not photographic full-colour printing.

Desktop and Support-Listed Models: K3 and K2
The K3 is a mains-powered 203 dpi desktop unit rather than a handheld. It covers 20–80 mm media, accepts die-cut and compatible continuous or fanfold stock, and is rated up to about 180 mm/s across a 24 V AC supply, at a weight around 1.22 kg. It appears on the official desktop compatibility list, which makes it the sensible pick for a fixed station running repetitive jobs.
The K2 is listed in the global hardware catalogue but has no public model-specific datasheet, so it cannot be recommended over the K3 on the strength of its name alone.
Search for the NIIMBOT K3 on Amazon
Legacy and Support-Listed Models: B18 and B21S
The B18 is an older thermal-transfer label maker using dedicated ribbon cartridges rather than D-series paper. It is relevant to existing owners hunting refills, and it is not a safe recommendation for a new purchase because cartridge supply needs checking first. Its supplies should not be assumed to fit the N1 simply because both use a ribbon.
The B21S appears in NIIMBOT's official desktop compatibility information but is not confirmed in the current US retail catalogue, and its resolution is unclear from the available specifications. Treating it as equivalent to the B21 Pro is a mistake; support-list inclusion proves software recognition, not hardware parity.
Two names should not be treated as confirmed NIIMBOT products at all. The D110S has no authoritative current product record. The D30 belongs to Phomemo, not NIIMBOT, and it turns up in mixed marketplace searches where brands get conflated.
NIIMBOT vs Brother and DYMO
NIIMBOT competes on size, price of entry and app simplicity, and it gives ground on media freedom and connectivity. Brother's QL-1110NWB is a 300 dpi, four-inch machine with USB, Ethernet, Wi-Fi, Wireless Direct and Bluetooth, and it prints standard 4×6 shipping labels while a D11 or B21 cannot. Brother's trade-off is media: DK rolls are a proprietary system of their own.
DYMO's current lineup separates narrow and wide clearly, and the 5-series adds electronic roll recognition not unlike NIIMBOT's approach. The LabelWriter 5XL is the DYMO model for 4×6 carrier labels, running USB and wired Ethernet with no Wi-Fi or Bluetooth at all. The full spread of models, from narrow 550 units to the 4XL and 5XL, is covered in our DYMO brand and lineup guide.
The pattern is consistent across all three brands: the moment a printer accepts authenticated or chipped consumables, long-term cost depends on refill availability, not on the price of the hardware.
NIIMBOT Refills and Compatibility: What Fits What
NIIMBOT splits consumables by printer family rather than by dimension. Use this as the starting point, then confirm the exact roll against the model list on the packaging.
| Consumable family | Models named as compatible |
|---|---|
| D-series 12 × 40 mm three-roll pack | D11, D110, D101 |
| D-series mixed-width and decorative rolls | D11, D110, D101 (dimensions permitting) |
| B21 / B1 / B3S 50 × 30 mm labels | B21, B1, B3S |
| Pro B-series media | B21 Pro, B1 Pro, B2 Pro |
| B4 100 × 150 mm shipping labels | B4 |
| N1 ribbons and cartridges | N1 |
| M2 / M3 thermal-transfer media | M2, M3 (SKU-specific) |
| K3 labels | K3 (dimension-specific) |
The 12 × 40 mm three-roll pack is the one refill with a confirmed exact listing, and it is the safest first purchase for a D11, D110 or D101. Everything else should be matched to the roll's stated compatible models rather than to its measured width.
The recognition layer is the reason a roll can fit mechanically and still be rejected. Community reports of third-party NIIMBOT media range from outright errors to successful printing after manual media selection, so compatibility is inconsistent rather than categorically impossible. When you compare the lifetime cost of a printer, weigh the roll families you can actually buy, alongside the general sizes and compatibility rules for thermal label stock.
Which NIIMBOT Should You Buy?
Match the printer to the width and the durability you need, and ignore the model numbers beyond that.
- NIIMBOT D11-H for fine detail on the smallest format: miniature text, small QR codes and 12 × 40 mm labels for jars, cables and bins.
- NIIMBOT D110-M for the cheapest route into everyday 8–15 mm labels, where 203 dpi is enough.
- NIIMBOT D101 when D11 labels are too narrow but a 50 mm product label is overkill.
- NIIMBOT H1S if you need adjustable label lengths from continuous stock on a narrow format.
- NIIMBOT B21 for price stickers, retail tags and product labels where the retro body appeals and 203 dpi is acceptable.
- NIIMBOT B21 Pro when small logos and fine text on 20–50 mm labels have to stay clean.
- NIIMBOT B4 when the labels are shipping labels up to 100 × 150 mm, and you accept the PDF and scaling discipline that comes with carrier output.
- NIIMBOT M2-H or M3 when labels must survive abrasion, heat or long-term exposure, and you are ready to buy ribbon as well as stock.
- NIIMBOT K3 for a fixed desk running repetitive jobs at speed on mains power.
A small seller shipping parcels daily usually ends up with two machines: a B-series or thermal label printer for products and inventory, and a dedicated 4×6 printer for carrier labels.
Frequently Asked Questions
Q: Can a NIIMBOT print Etsy, Shopify or Amazon shipping labels?
Only the B4-class models reach a standard 100 × 150 mm carrier label, and even there the workflow is printing a correctly sized PDF at actual size rather than a native account integration. Amazon FBA product and FNSKU labels are a different job from 4×6 box and pallet labels, and only the compact FNSKU format fits the 50 mm B-series.
Q: Does every NIIMBOT D11 print at 300 dpi?
No. The upgraded D11-H is 300 dpi, while the original D11 generation is 203 dpi. The two are sold under the same name, so confirm the resolution on the exact unit or listing before comparing print quality with a D110.
Q: Can I use third-party labels in a NIIMBOT printer?
Not with any guarantee. NIIMBOT runs a model-specific consumable system with media recognition, and third-party results range from rejected rolls to successful printing after manual media selection in the app. A roll that fits physically is not the same as a roll the printer will accept.
Q: Can I print from a Mac or PC instead of my phone?
Only on models that appear individually on NIIMBOT's desktop compatibility list, which includes several B-series models, the K3, M2-H and M3. The D11 and D110 are absent from it. USB-C charging does not imply USB data printing, and a Bluetooth connection does not make a NIIMBOT behave as a standard system printer.
Q: Is the NIIMBOT app free?
Basic label editing and printing are available without a subscription, while template libraries, special fonts and cloud functions may sit behind premium features depending on the model and app version. The B2 Pro's onboard template printing is a model-specific feature and should not be assumed across the range.
Conclusion
NIIMBOT covers three genuinely different jobs, and the model number tells you less than the media width does. For small, detailed labels on a narrow format, the D11-H is the pick, with the D110-M as the cheaper 203 dpi alternative on the same rolls. For product, price and barcode labels at 20–50 mm, the B21 delivers 203 dpi and the B21 Pro the sharper 300 dpi head. For anything resembling a carrier label, only the B4 belongs in the conversation, and even then the PDF workflow decides whether the job succeeds.
The buying decision does not end at the hardware. Check that your model appears on the official desktop support list if you want a wired workflow, confirm the roll family your printer actually accepts, and treat ribbon-based N1, M2-H and M3 machines as a separate ownership cost rather than a straight upgrade.
