I’ve got a Laptop, which behaves rather oddly, when it comes to configuring a printer.
Example 1: I open system-config-printer, click on “Add”, enter a device URI (“socket://192.168.9.5:9100”), click on forward. A dialog appears, showing “Searching for drivers” for a long time. Finally an error message appears: "There was an error during the CUPS operation: ‘Success’.
Example 2: I logon to 127.0.0.1:631, click on “Administration”, “Add Printer”, select “App Socket/JetDirect”, enter the connection “socket://hostname:9100”, click on “Continue”, enter a printer, name, and location, click on “Continue” again. The browser waits a long time, finally displaying the message
Unable to get list of printer drivers: > Success
Example 3: This one’s particularly reproducable:
[jwi@tarqeq ~]$ time lpinfo -m lpinfo: Success real 1m1.022s user 0m0.025s sys 0m0.014s
