Bug#603020: system-config-printer: Spurious 'printer not connected?' message?

[Sam Morris]

Package: system-config-printer
Version: 1.2.3-3
Severity: minor

Whenever I print to a printer shared on my network (via CUPS's automatic
discovery protocol), I get a notification message telling me that the
printer is not connected -- after the job is successfully sent to the
print server.
