In print queue for her network printers, for each
job, there was a "paused for authentication"
error.  Clicking on the "retry" choice resulted in
a username/password authentication.  Entering
valid credentials results in successful printing.
 I've been told that this is a known error, and it
is valid to check "remember" to not be prompted
for this again.  WE did not investigate fixing
this through the keychain.
