I was amazed that Epson still seem to sell 9 pin and
24 pin dot matrix
printers. Presumably some people still require multi-part carbon forms.
And the printer ribbon vartridge seems to be unchanged from the days of
the MX80, you can still get ribbons for that machine.
In Brazil, this is very common, although we are moving for a digital
invoice. And it is hellish complicated and expensive, but orders of our nice
govnmt.
