printer suddenly disappeared

[Buz Davis]

Thanks to Bret Stern and Ted Potter for their suggestions.  I found the 
problem and it is me, or at least my ignorance.

I have been working up to networking several computers, and since I 
figured they couldn't all be named "localhost.localdomain" had changed
the host and domain names.  I checked direct internet connection after 
such changes but didn't realize CUPS would be affected.  Obviously I 
have a lot to learn.

CAN computers be networked without changing their hostnames ?
