I seem to recall hearing a rumour that suggested that for years now, photocopiers have been leaving their serial number on the copies they produce. If true, and I am inclined to believe it, it follows naturally that something similar might happen with laser-printers and ink-jet printers. Ian Grigg <iang@systemics.com> wrote: R.A. Hettinga wrote:

I don't think this is new - I'm pretty sure it was published about 6 or 7 years back as a technique. iang --------------------------------- Post your free ad now! Yahoo! Canada Personals
