What’s next, single pen flatbed plotters?
BTW- I must be old. I still have an HP 11C…
…and I remember when we upgraded our single pen flatbed plotter to a state of the art 6 pen moving paper plotter complete with automatic pen selection. Instead of the plotter stopping and waiting for you to switch from the black pen to the red pen, the plotter would automagically put the black pen back into the carousel and pick up the red pen.
We were impressed.
