TCO 99 - Ecology Energy Emissions Ergonomics

Congratulations! You have just purchased a TCO'99 approved and labelled product! Your choice has provided you with a product developed for professional use. Your purchase has also contributed to reducing the burden on the environment and also to the further development of environmentally adapted electronics products.

Why do we have environmentally labelled computers?

In many countries, environmental labelling has become an established method for encouraging the adaptation of goods and services to the environment. The main problem, as far as computers and other electronics equipment are concerned, is that environmentally harmful substances are used both in the products and during their manufacture. Since it is not so far possible to satisfactorily recycle the majority of electronics equipment, most of these potentially damaging substances sooner or later enter nature.

There are also other characteristics of a computer, such as energy consumption levels, that are important from the viewpoints of both the work (internal) and natural (external) environments. Since all methods of electricity generation have a negative effect on the environment (e.g. acidic and climate-influencing emissions, radioactive waste), it is vital to save energy. Electronics equipment in offices is often left running continuously and thereby consumes a lot of energy.

What does labelling involve?

This product meets the requirements for the TCO'99 scheme which provides for international and environmental labelling of personal computers. The labelling scheme was developed as a joint effort by the TCO (The Swedish Confederation of Professional Employees), Svenska Naturskyddsforeningen (The Swedish Society for Nature Conservation) and Statens Energimyndighet (The Swedish National Energy Administration).

Approval requirements cover a wide range of issues: environment, ergonomics, usability, emission of electric and magnetic fields, energy consumption and electrical and fire safety.

The environmental demands impose restrictions on the presence and use of heavy metals, brominated and chlorinated flame retardants, CFCs (freons) and chlorinated solvents, among other things. The product must be prepared for recycling and the manufacturer is obliged to have an environmental policy which must be adhered to in each country where the company implements its operational policy.

The energy requirements include a demand that the computer and/or display, after a certain period of inactivity, shall reduce its power consumption to a lower level in one or more stages. The length of time to reactivate the computer shall be reasonable for the user.

Labelled products must meet strict environmental demands, for example, in respect of the reduction of electric and magnetic fields, physical and visual ergonomics and good usability.

Below you will find a brief summary of the environmental requirements met by this product. The complete environmental criteria document may be ordered from:

Whether you're printing reports, marketing materials, or presentations, the high-resolution output fulfills professional demands.

The D2842 series is well-known for its speed, providing rapid printing capabilities. With a high pages-per-minute (PPM) rating, these printers quickly churn out large volumes of documents without sacrificing quality. This efficiency is particularly beneficial in busy office settings, where time is of the essence.

In terms of connectivity, the HP D2842A and D2842W offer robust options, including USB and wireless capabilities. This flexibility allows users to print directly from their devices, whether they are connected through traditional USB or via Wi-Fi, enabling a seamless integration into modern workspaces. The D2842W stands out in this regard, as its wireless functionality enhances mobility and convenience.

Paper handling features are also noteworthy. The models support different paper sizes and types, accommodating everything from standard letter sheets to envelopes and labels. Their adjustable paper trays make it easy to transition between print jobs without downtime, while optional additional trays can further expand capacity.

Energy efficiency is an essential characteristic, with both models designed to consume less power without compromising performance. Additionally, HP’s Auto-On/Auto-Off technology reduces energy usage and contributes to a lower carbon footprint, making these printers an environmentally friendly choice.

Finally, user-friendly features such as easy installation, clear LCD displays, and intuitive controls make the HP D2842A and D2842W accessible to users of all technical levels. These attributes, combined with reliable performance and consistent output, ensure that both models remain relevant and competitive in the rapidly evolving landscape of printing technology. Whether for small offices or larger corporations, these printers deliver impressive results that meet the demands of today's professional environments.
