But this is quite a new model and I don't remember seeing this technology anywhere else for a long while, so perhaps they had to wait for some patent to expire?
These machines also have swappable tools (effectively a two tool changer).
I think ultimately the plotter largely became the vinyl cutter.
I remember using flatbed plotters with a "static-cling" button. (maybe HP?)
you clicked the button out, put paper on the flatbed, then clicked the button in and a static charge sucked the paper down and held it in place.
You would generate your plots using a language that could select various color pens, move to x1,y1, pen down, move to x2,y2, pen up, etc...
I think better printers and then inkjets are what finally killed them off.
