Try to get a laser with automatic duplex printing if you want to save paper. With manual duplex printing mistakes can cost a significant proportion of paper and may require significant amounts of effort to do correctly. I currently have a Brother HL-2140 (also has HL-21 model number) and it has 'manual duplex'. This means if I want to save paper I have to mark a corner of the first page before printing and see what orientation it prints compared to that mark (it is not intuitive). I have been printing one page at a time because of this, although now I have written this down I realise I could do better.
