I've discovered some interesting things about the little $400 laser printer in the basement. It has its own web server! You can telnet to it! And, if you ping it, you lose about 1/4 of the packets.
The Ping problem, I expect, may explain why the printer has become very, very slow. But why would I lose 1/4 of the packets (and not ALL the packets) on a very quiet, lazy LAN? Got a hint? Email me!
