A long time ago, I worked at the head office of an organisation that was supposedly at the forefront of networking technology of the time. The volume of e-mails was relatively low compared to paper correspondence and the office manager insisted that they were printed off and included in the daily correspondence log for future reference along with copies of the incoming post. I once had to look something up in the archive and found it was way larger than might be expected as it contained a large number of PostScript attachments that had been dutifully printed out despite the fact that the office owned printers were only capable of PCL 3.
