I shared my experience in this comment:
Unfortunately all brands have problems. The most problematic for me have been Epsons, Lexmark and Brother. The best have been Canon. I have loved the canon printers i have had. HP laser jet printers tend to be good. If you have an HP you might need drivers that HP doesn’t provide. You might find this useful.

What I think is interesting in this story from Gizmodo is the fact that they wear a yellow badge. Wasn’t Germany famous for making its Jewish citizens wear a yellow star? Did someone skip their history class?
