By 2011, HP expects to improve the overall energy efficiency of HP ink and laser printing products by 40 percent, relative to 2005.1
Each tip here reflects an on-going determination to drive down energy consumption across our products.
As a result, many new products use less energy than their predecessors. And, while many products use energy even when off, HP LaserJet and Inkjet products consume less than 1 watt of energy in off mode.
If your data center is the prime target for reducing your carbon footprint, it’s time to expand your view beyond servers and storage. The many printing and imaging devices across your company can also boost your energy-saving potential.
As part of the HP Eco Solutions Program, we’ve compiled these top tips for power-smart printing and imaging. Based on energy-efficient technology and innovations from HP, they can help you reduce your environmental impact to reap the energy-saving rewards.
HP Carbon Footprint Calculator for printing. This free tool helps you evaluate the energy consumption, paper use, carbon output and associated monetary costs of your printing environment based on the geographical energy assessments for 146 countries.
Do head-to-head comparisons of specific printers or compare the carbon footprint of your current printer fleet to new, optimized fleets (includes HP and/or competitive products). Check it out to see how you can reduce your carbon footprint by as much as 30 percent.
ENERGY STARŪ qualified products. Many HP Inkjet and LaserJet products meet new requirements set by the Environmental Protection Agency’s ENERGY STAR program – the most recognized national symbol for energy efficiency in the U.S.
- HP ENERGY STAR qualified Inkjet multifunction/all-in-one devices are over 55 percent more energy efficient than non-qualified standard models2
- HP ENERGY STAR qualified LaserJet multifunction/all-in-one devices are over 20 percent more energy efficient than non-qualified standard models2
- HP ENERGY STAR qualified LaserJet printers are over 10 percent more energy efficient than non-qualified standard models2
Automatic sleep and wake modes. With HP Web Jetadmin, a remote network print and imaging peripheral management software tool, you can pre-set automatic sleep and wake modes on printing devices across the company to help save energy. Many HP LaserJet printers have an automatic sleep mode.
For further reductions, turn printers off on nights and weekends. The U.S. Department of Energy states that companies can save up to 66 percent of energy costs associated with printing and imaging equipment by doing so.
Instant-on Technology. During “power save” mode, idle printers consume less energy, but this can add to print time. Built into many HP LaserJet printers, Instant-on Technology provides up to 50 percent energy savings over traditional fusing, while delivering a first page-out in seconds – up to 50 percent faster than competitive products.3
How much impact can that make on your carbon footprint? A lot: The use of Instant-on Technology in HP LaserJet printers has reduced emissions by 6.4 million tonnes of CO2 to date – the equivalent of removing nearly 1.4 million cars from the road for 1 year.4
HP Instant-on Copy. Compared to copiers with fluorescent tubes, select HP LaserJet products using Instant-on Copy with LED-based technology consume four times less energy in low-power mode and 1.4 times less energy in copy mode. Copy jobs begin in a matter of seconds from low-power mode, even first thing in the morning.
HP low-melt toner. Designed to melt at lower temperatures, this toner helps reduce energy consumption without sacrificing print quality or speed. Look for this feature on select HP LaserJet printers.
HP Managed Print Services can help you right-size your imaging and printing fleet with fewer, more power-efficient devices that align printing resources with user needs and your energy reduction goals.
A pre- and post-analysis of some HP managed print services customers’
imaging and printing operations reveals an energy savings of between 30 percent and 80 percent.

(1) Average energy efficiency per unit shipped for 2005 using industry standard measurement benchmarks. Efficiency is defined in terms of kWh (using the Total Electricity Consumption Method)/pages per minute). Efficiency is defined in terms of kWh (using the Total Electricity Consumption Method)/pages per minute). These families represent more than 32% of inkjet printers and more than 45% of LaserJet printers shipped in 2005.
