Two free guides are available on the web to help printers wanting to be greener. The first is  published by Envirowise - How to become a green printer (ref EN281). This was published in 2001, and helps printers to use good environmental practices to save money and to demonstrate their 'green' credentials to customers. A new version is currently being developed and will be available shortly. Envirowise have also put together a podcast The Greening of Print, available from their website.
