The best label maker for canning jars is a thermal label printer whose labels survive a damp pantry: the listing should state round or transparent label sizes and labels that stand up to moisture and handling. We compared four thermal label printers by stated label sizes and formats, connectivity, battery, print resolution and warranty term, using only what each listing publishes. All four print monochrome at 203 DPI, and every one works over Bluetooth.

How we scored them
The Office Score weighs performance (label sizes and formats for jars, connectivity and print features), build (battery, weight and materials), value for the stated specs, safety and warranty. For a label maker, safety means stated safety-relevant label features; only the TYPONOS PM240 states any, with labels listed as waterproof, oil-resistant, tear-resistant and BPA-free. All four listings state a warranty term: the two NIIMBOTs at 2 years and the Rongta and TYPONOS at 1 year.
| Product | Office Score | Perf. /35 | Build /25 | Value /25 | Safety /10 | Warranty /5 |
|---|---|---|---|---|---|---|
| TYPONOS PM240 | 9.8 | 33 | 22 | 22 | 8 | 2 |
| NIIMBOT B2 | 9.6 | 32 | 21 | 22 | 0 | 3 |
| NIIMBOT B1 | 9.5 | 28 | 20 | 20 | 0 | 3 |
| Rongta R22 | 9.5 | 28 | 20 | 20 | 0 | 2 |
Scores run from 9.2 to 9.8: each product’s point total is placed on that range, so more points always means a higher score.
How to choose the best label maker for canning jars
Start with the label shapes, not the printer
A jar lid takes a round label and a jar side takes a rectangular or transparent one, so check which shapes the listing states. The TYPONOS PM240 includes three rolls, 50×30 mm white, 50×80 mm white and 50 mm round white, and works with 1 to 2 in square, round and transparent labels, which the listing calls ideal for glass jars. The NIIMBOT B2 supports 20 to 50 mm widths in white, colored, round and transparent. The NIIMBOT B1 and Rongta R22 both ship one 2×1.18 in roll, with widths of 0.8 to 2 in and 0.63 to 2.13 in respectively.
Match the label to a damp pantry
Canning jars live in humid pantries and get wiped down, so the label material matters as much as the print. The TYPONOS labels are stated waterproof, oil-resistant, tear-resistant and BPA-free, the only such claims here. The other three listings state no label durability claims, so treat their labels as standard thermal paper unless the listing says otherwise. For the rest of the home office, see our label makers and shredders.
| Label maker | Labels included | Connectivity | Battery |
|---|---|---|---|
| TYPONOS PM240 | 3 rolls: 50×30, 50×80, 50 mm round | Bluetooth, USB | 1500 mAh, 100-day standby |
| NIIMBOT B2 | 1 roll: 50×30 mm | Bluetooth, USB | Not stated |
| NIIMBOT B1 | 1 roll: 2×1.18 in | Bluetooth | 1500 mAh, 5-hour printing |
| Rongta R22 | 1 roll: 2×1.18 in | Bluetooth, phone only | 1500 mAh, 4-hour printing |
Figures as stated in each listing. Only the TYPONOS lists a standby time; the others state printing hours or nothing.
Phone, PC or no screen at all
The NIIMBOT B1 connects to iOS, Android and PC, while the Rongta R22 is phone-only and states twice that it does not work with computers. The TYPONOS PM240 and NIIMBOT B2 add a USB connection for a PC alongside Bluetooth. The NIIMBOT B2 goes further with one-button offline printing, which prints real-time dates and templates without opening the app, handy for dating each batch as you fill the jars.
Read the warranty line
All four state a term. The NIIMBOT B2 and B1 carry a 2-year warranty description, though the B1 bullets separately describe a 12-month free replacement service, so ask the seller which applies. The Rongta R22 and TYPONOS PM240 each state 1 year. A label printer’s battery and print head do the wearing, so the longer stated term has real value here.
