Selection framework
| Decision | Starting point |
|---|---|
| Print method | Direct thermal for normal parcel life |
| Width | 4-inch class |
| Resolution | 203 dpi; 300 dpi for smaller mixed formats |
| Connection | USB for one station, Ethernet for shared use |
| Media | Carrier-compatible direct thermal labels |
Validation checklist
- Print real labels from every carrier platform
- Scan barcodes after application to production cartons
- Measure peak labels per hour
- Document reprint and media-change procedures
Final recommendation
Request samples and test the exact printer, settings, ribbon, facestock and adhesive on the production surface. Verify barcode quality after the complete environmental cycle, not only immediately after printing.
