Comparison of Technologies: Ink versus Laser: Energy Consumption
DC determines energy consumption assuming the following conditions
- Printers are switched on 24 hours a day.
- Print jobs are 100 pages of text and graphics per day.
- For reasons of simplification this is done as one single print job.
In case of many small print jobs a day, results for the laser printer would be much worse, due to the unavoidable heating-up of the fuser for every single job, boosting energy consumption.
