Zuvo Thermal Shipping Labels - 6x4 - 500 Pack

No, these are thermal labels and do not require any ink or toner. They print using heat from a compatible thermal printer.

The labels measure 6 inches by 4 inches (150 mm x 100 mm), which is a standard size for shipping and postage labels.

These labels are designed specifically for direct thermal printers. They are not compatible with inkjet or laser printers.

Each pack contains 500 labels.

The labels have a durable finish resistant to smudges and scratches, but they are not waterproof. Prolonged exposure to moisture may affect print quality.

Printed labels are designed for shipping and should last through transit. For long-term archival, avoid direct sunlight and extreme temperatures.

Ensure the label roll is loaded correctly and the print head is clean. Check printer settings for appropriate darkness and speed. Verify you are using a direct thermal printer.

Clean the surface of the package before applying the label. Ensure the label is applied smoothly without wrinkles. If applying in very cold or humid conditions, allow time for the adhesive to bond.

Check that the label guides in the printer are adjusted properly for the width of the roll. Ensure the label roll is not tangled or obstructed.

Allow the printed label to cool for a few seconds before handling. Ensure the thermal printer's temperature is set appropriately; excessively high heat can sometimes affect smudge resistance.
