Well, I seemed to be making progress. My son put this computer together 
for me, and installed, Ubuntu, setting up a user called "Sir". I then 
added a user called brian (since that's me; historical explanation 
omitted). It appeared (the other day) that I needed to enter Sir's 
password for access to the CUPS stuff. I couldn't see how Sir was 
_distinguished_ in the users list, which left me puzzled. Worse (or 
better, depending on how you look at it), as far as I can see today, I 
can enter my own password and change the printer settings, so a 
different mystery.

Anyway, I am trying get printer sharing to work. I have two computers, 
Bowen and Chopin, on a LAN. Bowen (xubuntu) has a printer (which works), 
and access to the CUPS web interface, in which I have set the printer to 
"published". Do I understand correctly that this means "available to 
other computers on the LAN"?

Chopin is this Ubuntu box, and the (similar set of) gnome printer 
settings I have set to "Show printers shared by other systems". But I 
see no printers.

Is there something else I should need to do?

More generally, I've tried looking at the "Network" admin dialog boxes, 
but they are extremely terse. How can I tell whether anything is 
communicating? E.g. ping chopin says "unknown host", so perhaps not, yet.

Help! (Of course, a pointer to the best place to read about this is 
probably optimal.)

Thanks...
