Original HP Toner Cartridges are engineered to work seamlessly with HP LaserJet printers to support long-lasting, high-quality output. During printing, toner particles—made from a specific blend of plastic polymer and additives—are heated until they melt and then fuse firmly to the paper. This controlled fusing process helps maintain sharp text and clear graphics over time.

A key concept here is toner archive ability—the toner’s ability to maintain quality over long periods. This helps prevent fading or smudging and supports long-term readability for documents such as contracts, records, and certificates.

To validate durability claims, HP LaserJet printers and Original HP Toner Cartridges are tested against the ISO 11798 standard for permanence and durability. This standard evaluates:

• Lightfastness (resistance to fading from light)
• Water and wear resistance
• Heat and folding tolerance

Many HP LaserJet printers and Original HP Toner Cartridges comply with ISO 11798, with testing performed by RISE Research Institutes of Sweden AB. Active certificates are available on the RISE public website.

Because toner composition is central to these permanence characteristics, HP’s durability testing and certifications are based on Original HP Toner Cartridges. When non-HP cartridges are used, HP cannot guarantee that the same durability standards will be met.

Original HP Toner is designed to help your documents withstand everyday exposure to water and light in office environments.

Waterfastness:

• Original HP Toner is made from plastic that is not water soluble.
• Under typical office conditions, pages printed with Original HP Toner should not streak or run when exposed to water.
• Water-resistance properties on plain paper are covered as part of the ISO 11798 standard testing.

Lightfastness and aging:

• The ISO 11798 standard also includes tests for lightfastness and accelerated aging.
• These tests help ensure that both monochrome and color laser prints resist fading from light exposure over time.

For documents that will be displayed (such as photos or diplomas), HP recommends displaying prints under glass and avoiding long-term direct sunlight to help maintain appearance and readability.

To extend the life and readability of your printed documents, consider a combination of the right hardware, supplies, and storage practices.

1. Use compatible printers, toner, and paper

• Print with an HP LaserJet printer using Original HP Toner Cartridges, which are tested together for durability and permanence.
• Choose paper that meets ISO 9706 for archival media when you need very long document life.
• HP Home & Office Papers are acid-free according to ISO 9706, supporting long-lasting documents.

2. Rely on tested durability standards

• Many HP LaserJet printers and Original HP Toner Cartridges comply with ISO 11798 for permanence and durability (lightfastness, water and wear resistance, heat and folding tolerance).
• HP products are also tested by Papiertechnische Stiftung (PTS) under the German DONot test, which assesses resistance to chemicals, water, tape, folding, rubbing, aging, forgery, light, and transfer of recording.
• Sample PTS DONot certificates are available at ptspaper.de/en, and ISO 11798 certificates at the RISE public site.

3. Follow storage and handling best practices

• Avoid placing documents in direct sunlight or areas with long-term intense light exposure.
• Keep documents away from extreme environmental conditions such as high humidity, excessive heat, or very low temperatures.
• For important display items (photos, diplomas, certificates), display under glass to help protect against dust, handling, and environmental factors.

By combining Original HP Toner, suitable archival paper, and careful storage, you can reimagine your print workflows for more reliable, long-term document preservation.
