The argument to justify its replacement needs to be something along the lines of the new plotter will output faster and save X hours a day which is equal to Y hours of time over a year. Not that the new one supports IPv6 and yeah that's about it. Oh the new one also supports TLSv1.3 to make sure your plots can't be intercepted by your cube neighbor as you walk across the office.

I know that. What I'm trying to say is that many companies aren't 
willing to throw away working equipment to gain a nebulous (to them) 
software feature like IPv6 that doesn't improve on its hardware 
functional state.
