Why Printing Postage Labels Matters
Printing postage labels is the final step before a package reaches the carrier, and mistakes here create delays that no sender wants. A misaligned label, smared ink, or incompatible paper stock can result in unreadable barcodes, returned mail, or lost parcels. Whether you ship a handful of orders a month or run a high-volume e-commerce operation, getting the label right matters for cost, speed, and reliability.

Printers and Print Settings for Postage Labels
Not every printer handles postage labels well. Thermal printers are the standard for high-volume shipping because they use heat to print on specialty labels without ink, reducing smearing and ongoing costs. Inkjet and laser printers work for lower volumes but require the correct label stock and print settings.
Thermal Printers
Direct thermal printers are the most common choice for shipping labels. They print quickly, resist moisture better than ink, and pair easily with shipping software. Look for models with at least 203 dots per inch (DPI) resolution and a print width of at least 4 inches to accommodate standard label formats.
Inkjet and Laser Printers
If you use an inkjet or laser printer, select labels rated for your printer type. Inkjet labels absorb ink; laser labels use heat-fused toner. Printing on the wrong stock causes smearing, peeling, or jamming. Always run a test print on plain paper first to check alignment before committing to adhesive labels.
Key Print Settings
- Set print quality to the highest available resolution for sharp barcodes.
- Disable any "fit to page" or "auto-rotate" scaling options.
- Match the paper size in your print dialog to the exact label dimensions.
- Print on the label side of the sheet, with the printable surface facing the correct way.
Choosing the Right Label Stock
The label itself affects durability and readability. Shipping labels should be at least 4 inches by 6 inches for standard carriers, though some services accept smaller sizes. Look for labels with a permanent adhesive rated for the expected conditions, including temperature changes during transit. Matte-finish labels reduce glare and help scanners read barcodes more reliably than glossy stock.
| Label Type | Best For | Durability |
|---|---|---|
| Thermal transfer | High-volume, long-term storage | High resistance to smearing and moisture |
| Direct thermal | Standard shipping, short-term use | Moderate; can fade under heat or light |
| Inkjet-compatible glossy | Low-volume, branded returns | Moderate; smears if exposed to moisture |
| Laser-compatible matte | General shipping, barcode clarity | High; resistant to fading and moisture |
Software and Formatting Tips
Most shipping platforms generate labels in PDF or ZPL format. When printing, use the native file format provided by the software rather than converting it, as conversion can distort sizing and barcode data. Check that the barcode starts and ends at the correct margins on the label, and confirm that the tracking number is legible without touching the edge of the adhesive area.
Common Mistakes to Avoid
- Peeling or re-sticking a label after it has been applied.
- Printing on the wrong side of the label sheet.
- Using labels with a removable or temporary adhesive for outbound shipping.
- Ignoring software updates for shipping platforms that may change label dimensions.
- Overloading a thermal printer with dense graphics that slow print speed and reduce clarity.
Testing Before You Ship
Before running a full batch, print a single label and scan it with a barcode reader or a smartphone scanning app. If the scanner reads the tracking number correctly, the label is ready. For bulk jobs, test the first label from every new roll or sheet of labels, since adhesive and print quality can vary between batches.
