Native resolution
Every label is laid out on the B1's 8 dots/mm grid. Rules, frames, QR modules and barcode bars are whole dots, never anti-aliased.
For the Niimbot B1
Labels that print sharp.
NiimLabel draws every label on the printer's own grid of 8 dots per millimetre and fits each letter to the dots, so text comes out cleaner than the official app. On your iPhone, iPad, Android phone or tablet, Mac and PC.

Same printer, same 203 dpi
The difference is how the dots are chosen.
Most label apps draw text at screen resolution, shrink it, then round it to black and white, so stems smear and hairlines break. NiimLabel renders at the head's native resolution and places every letter where its strokes land squarely on dots. Both images below are the exact bitmaps sent to the printer, magnified 4×.
What it does
Built around the print head.
Letters fitted to the grid
Each glyph is tried at four sub-dot offsets and placed where its stems fall cleanly on dots. Up to a third less smeared ink on small text.
What you see is what prints
The preview shows the label as ink on paper, or every single dot. It warns you about text too small or too thin for 203 dpi.
Templates that reflow
Fourteen designs that adapt from 30×15 to 50×80 mm, shrinking type together and dropping secondary lines on tiny labels.
Batch printing
Paste a list, or snap a photo of your shelf or a handwritten list and let AI write one clean label per item, translated if you like. Preview the set and print it as one job.
Make it yours
Change fonts, spacing and frames; add text, QR codes, barcodes and logos. Or describe a style and let AI design three for you.
Calibrate your roll
One button prints a test label at three darkness levels, so you can see which one keeps hairlines intact and small text open.

Questions
Good to know.
Can any app make the B1 print perfectly smooth text?
No. The B1 burns a grid of dots, 8 per millimetre, black or nothing. What software controls is which dots burn, and that is where NiimLabel puts all its effort. At arm's length the result reads as smooth; under a loupe every 203 dpi printer shows its dots. The B1 Pro has a 300 dpi head.
Which printers does it work with?
It's designed and tuned for the Niimbot B1. Other Niimbot models connect through the same library and may print, but layouts assume 203 dpi.
Does it need an account or the internet?
Not to start. You begin as a guest; add your email (no password, just a one-time code) to keep Pro across devices. Designs stay on your device.
Is this an official Niimbot app?
No. NiimLabel is an independent app, not affiliated with or endorsed by NIIMBOT.
