Researchers at the University of Cambridge in the UK have developed a method for removing laser-printed text from paper. It could mean devices used for security, recycling or both.

The technique worked by using the laser beam to apply the right level of heat for a mere four billionths of a second. It isn’t a case of the words dropping off the page: the heat vaporized the toner, with the resulting gas being captured in a filter. Allwood says the technique worked on a range of toners and does not damage the paper or leave it unable to “receive” toner in the future.
