This is no problem, except device-uri or similar important string is wrong.
Only the involved printer is affected.

Only the printers before this error works.


Never saw a corrupted printers.conf (we have more than 20 cups servers and
300 printers). You can avoid corruptions with using reiserfs4 or any other
file system which supports atomic transactions. Also making a backup of
your lpadmin commands may be a good idea.


PS: We store our printers and default options in a SQL database.
