I think it makes a lot of sense to work from digital plots in these days, not only is it environmental friendly, but it is also a better way to keep everyone up to date on the latest version of the plot. Another advantage is that you can make annotations for everyone to read (making a correction in patch on the pdf, stored in dropbox/Google Drive updates for the whole team immediately)
If you really need to produce a plot on paper, nothing prevents you or your client from printing out the pdf.
