Yes, I've seen this before, and it can actually be helpful. You have a 
connection loose or a termination problem somewhere on your network.

We have a very large AppleTalk (LocalTalk?) net that is hooked together
by Farallon Star Controlers. We had a bad Star and witnessed the same
behaviour you mentioned. 

Looking at the flashing LaserWriters can actually be a cheap diagnostic tool. 
The chooser must check each of the printers every several seconds.
