Core Features
Label Sizes
The five supported thermal label sizes, feed-direction behavior, and media auto-detect.
Last updated 2026-05-23 · Applies to NotBot 1.3.4+
NotBot supports five standard thermal label sizes. Pick the size that matches the physical labels loaded in your printer.
Available sizes
| Size | Dimensions (W × H) | Best for |
|---|---|---|
| 1x1 | 1" × 1" | Compact nameplate or sticker. Niche. Most sellers don't use this. |
| 2x1 | 2" × 1" | Small buyer-number labels. Username and number, nothing else. |
| 1x3 | 3" × 1" | Narrow landscape. Number and username side by side. |
| 2x3 (default) | 3" × 2" | Standard. Fits username, item name, number, and a badge. |
| 4x6 | 6" × 4" | Large shipping-size labels. Plenty of room for full item names. |
The default is 2x3. Most sellers run their entire show on 2x3, and it fits well on Rollo, Munbyn, Jadens, and DYMO thermal printers.
Setting the size
The label size lives in Settings → Print Settings → Label Size. Changing it switches every event type to the new size. If you want a specific event type (for example, Buy It Now or giveaways) to print at a different size, you can override that per event under Settings → Advanced → Per-Event Routing. The buyer/box label can also be pinned to its own size under Buyer / Box Label Format.
Feed direction matters
Thermal printers feed labels in one of two orientations:
- Landscape: the long side of the label feeds first. Examples include Rollo and Munbyn.
- Portrait: the short side of the label feeds first. Examples include DYMO LabelWriter and Brother QL-series.
NotBot defaults to landscape for every label size, with one exception. On macOS, the 4x6 size defaults to portrait because that matches how 4x6 shipping-style rolls feed on Mac. Every other size on macOS, and every size on Windows, defaults to landscape.
If your prints come out rotated or chopped off, switch the Feed Direction in Settings → Printer Configuration. The option appears once a printer is selected. The change is per printer, so if you have multiple printers configured you can set each one independently.
Media / roll auto-detection
Most thermal printers report their available label sizes to your operating system. NotBot reads that list and lets you pick from it in Settings → Printer Configuration → Media / Roll. Leave this on Auto-detect unless labels are printing at the wrong size. Picking the exact roll size in the dropdown almost always fixes it.
This is also a per-printer setting.
Custom paper sizes
If your printer supports a non-standard paper size (often the case with thermal printers loaded with continuous-feed rolls), you can pick that size from the Media / Roll dropdown. NotBot will pass that page size to the print driver when sending labels.
Buying labels
Buy removable labels, not permanent ones. Removable labels peel off cleanly without leaving adhesive residue. Permanent labels can tear, stain, or damage what they're stuck to, especially on fabric.
Don't stick labels directly on the product when you can avoid it. A sticker on the outside of a shirt or other piece of clothing reaches the buyer attached to their item. We've seen complaints about this. Stick labels on the box, mailer, or polybag the item ships in instead. If you're using NotBot's buyer/box method, that's already how it's designed: one label per buyer's shipping container, items go inside.
If the item really does need its own label (multi-item shows, sorting in a bin, etc.), use removable labels and attach them to a hang-tag or place them on the inside of a polybag rather than on the product itself.
