Article mentions dot matrix printers.. I've thought a few times that if there was an easy way to get a daisy wheel printer I would. There are situations where it would be neat to be able to set one up as a permanent record and as a fax substitute. I have multiple homes, and it would be an easy way to send a message to non-technical people living in the houses that I have servers sitting in where I might be in another country for years at a time.
In this book (http://en.wikipedia.org/wiki/The_Cuckoo%27s_Egg_(book)), Stoll talks about hooking up unix terminals to daisy wheel printers so he can review input later on.
