# QR codes on Dymo and Brother label printers

> Consumer label printers print reliable QR codes within hard limits — about 300 dpi on Dymo LabelWriter and Brother QL machines, 180 dpi on entry P-touch tape printers, and roughly 9–18 mm of printable height on 12–24 mm tape. That caps capacity — on 12 mm tape even a version 1 code is marginal.

## Know which machine you have

Three families behave very differently:

| Family | Technology | Resolution class | Print medium |
|---|---|---|---|
| Dymo LabelWriter | Direct thermal | ~300 dpi | Paper die-cut labels — **fades** |
| Brother QL | Direct thermal | 300 dpi | Paper labels — fades; some film stock |
| Brother P-touch (TZe tape) | Thermal transfer onto laminated tape | 180 dpi entry models, up to 360 on higher ones | Laminated plastic tape — durable |

Direct thermal paper labels fade in heat and light within months — the mechanics are on
[direct thermal vs thermal transfer](/docs/print/direct-thermal-vs-thermal-transfer-for-qr).
P-touch is the odd one out and the durability winner: the print is fused under a clear
laminate layer, so TZe labels shrug off water, abrasion and sunlight for years — the right
choice for asset tags, [plant tags](/qr-codes-on/plant-tags) and cable labels.

## Tape width sets the code budget

TZe tape prints roughly 70–75% of its width — the rest is margin the mechanism cannot
reach:

| Tape | Printable height | At 300 dpi, 4-dot (0.34 mm) modules | Verdict |
|---|---|---|---|
| 12 mm | ~9 mm | 26 module-widths — under the 29 a version 1 code needs with [quiet zone](/glossary/quiet-zone) | **Marginal** — needs 3-dot modules |
| 18 mm | ~13.5 mm | 39 module-widths → version 2 (25 + 8 = 33) fits | Short URLs only |
| 24 mm | ~18 mm | 53 module-widths → **version 7** (45 + 8 = 53) just fits | Comfortable |

On an entry 180 dpi P-touch the dot is 0.141 mm, so a 4-dot module is 0.56 mm — 18 mm of
print height carries only a version 1 symbol. The practical rule for tape printers:
**24 mm tape, shortest possible payload**. A long URL that pushes the symbol to version 6+
will not fit at scannable module sizes —
[why longer URLs make denser codes](/docs/spec/why-longer-urls-make-denser-codes) — so
check the pairing in the [size calculator](/size-calculator) before committing a roll.

## App QR features vs importing an image

Dymo Connect and Brother P-touch Editor both have built-in QR objects. Use them when they
work: like a Zebra's [native command](/docs/print/thermal-printer-qr-codes), the software
renders modules onto the printer's dot grid directly. Two honest caveats: the built-in
objects expose little control (error correction level is often fixed or hidden), and some
versions render QR at the object's on-screen size rather than a dot-exact size — always
scan a test label.

Importing a PNG works well **if the pixel count maps to whole dots**: generate the code at
exact final pixels — e.g. `https://useqr.app/api/v1/qr?data=…&size=132` for a 33-module
symbol at 4 px per module — and place it at 100% scale, never stretched to fit. A stretched
image gives fractional modules and flaky scans. For runs of many labels, generate the
images with the [bulk generator](/bulk) or the
[keyless API](/docs/developers/free-qr-code-api-no-key) and mail-merge them in the label
software.

## Verify before you print fifty

Tape is expensive per centimetre. Print one label, scan it from ~15 cm with two phones, and
confirm the payload matches with the [validator](/validate) logic — exact string, not just
"a page opened". Then run the batch. Fifty mislabelled sample jars teach this lesson only
once.

## FAQ

### Can a Dymo LabelWriter print QR codes?
Yes — Dymo Connect has a QR object and imported PNGs work at exact pixel sizes. But LabelWriter labels are direct thermal paper: they fade within months in heat or light, so use them for short-lived labelling only.

### What Brother tape width do I need for a QR code?
24 mm tape is the comfortable choice, fitting up to a version 7 code at reliable module sizes. 18 mm handles short URLs; on 12 mm tape even a version 1 code is marginal — use it for text and put the code elsewhere.

### Why is the QR code from my label maker blurry?
Usually a stretched image: resizing a PNG to fit the label creates fractional modules on the printer's dot grid. Generate the image at the exact pixel size and place it unscaled, or use the app's built-in QR object.

### Are P-touch QR labels durable?
Yes. TZe tape is thermal transfer under a clear laminate and resists water, abrasion and UV for years — far outlasting direct thermal paper labels from LabelWriter and QL machines.
