Hello, and IIRC there was a C-64 color printer that used 4 ballpoint

available that would use it, though.  Sincerely,

It was marketed as "printer/plotter", which was true. From certain point
of view :-)

It was good for plotting line graphics and it had the ability to plot
text, with a nice vector font...

You can find the font about mid-page down there.

But I would not recommend to use the plotter to colour-fill any sizeable
paper area. Or "print" longer BASIC listings (as I myself tried back in
the days :-)
