8. Label Paper
For best results, we recommend using official NIIMBOT supplies. Our specially designed label products improve print performance and prevent premature wear of the printhead.
8.1 Verifying Label Compatibility
- With ordinary thermal label paper, you can scratch the print surface of the medium with a fingernail or pen cap.
- Official NIIMBOT thermal label paper offers improved thermal-resistant and waterproof performance.
- Use a lighter to heat up the paper to test whether any black marks appear on the label paper.
Notiz:
- If a black mark appears on the paper, then the label is made from a thermal material and is supported by this printer.
- If there is no black mark, then the label is a thermal transfer label and requires the use of a carbon ribbon, which is not supported by this printer.
8.2 Label Type
| Etikettentyp | Paper Feed Type | Beschreibung |
|---|---|---|
| Non-continuous roll | Abstand | Each label is separated by gaps. |
| Schwarzer Fleck | Pre-printed black marks on the back of the media are used to indicate label separations. | |
| Non-continuous roll | Transparent | The labels are made from a transparent material, and each label is separated by gaps. |
