Electric and electronic devices contain different materials which can be dangerous for environment and human’s life. These materials are mainly heavy metals (Hg, Pb, Cd, Cr) and chemical compounds of chlorine (CHC, PCB, PCV). The research was focused on analysis of possibilities of limitation of neagitive impact on environment by ecodesign. Computer printer was taken as an example. It’s impact on environment was estimated by analizys of several variants of exploatation and disposal. The Life Cycle Analysis method with Sima Pro 7.0 program was considered to be very useful. This method allows to compare different variants and to take into consideration environmental and economical criteria.
