MUNBYN 2.25 × 1.25 in Direct Thermal Labels (1,000 per roll)
The 2.25 × 1.25 in size is a common barcode/SKU label, and MUNBYN's 1,000-label roll is a clear, documented option for generic direct thermal printers. Without a published core or diameter, internal-roll printers are a conditional fit.

Analysis
Width check
2.25 in is within the published minimums of every generic printer in our catalog, including the iDPRT SP410 and POLONO PL60 (2 in minimum).
Compatibility notes and common mistakes
External-feed printers need a holder for rolls.
- Forgetting to change the label size in your software from 4x6.
Alternatives
Phomemo 40 × 30 mm White Labels (M110 series)
Small labels for the portable M110.
Final recommendation
A practical second label size for generic thermal printers.
