Using environmentally conscious printers and paper can help reduce consumption of natural resources, and leave small environmental impact. Consider using tree-free and high post-consumer content papers and because paper whitened with chlorine is related to the production of dioxins and other highly toxic compounds, use Process Chlorine Free (PCF) papers instead, as dioxins can cause cancer, pollute waterways and cause harm to fish and wildlife. Unbleached paper can have a professional look, and more natural looking paper makes a eco-friendly statement about a business and the environment. Also look for a printer that uses non-toxic inks and toners, such as those made from soy, oil and resin. Earth friendly printers will print in small batches if requested and use locally made paper. There are many sources for paper other than conventional lumber as well, consider tree-free materials such as rice, hemp, and other plant fibers, to leave a lighter impact on the environment.
