The printer configuration is incorrect or the printer no longer exists.

A DESCRIPTION OF THE PROBLEM :
In the dropdown menu of the printers, special characters in the printer names are not displayed properly, but their "UTF-8 codepoint values" are shown. For example, the printer "äbc" (with the German umlaut "ä" as the first character) is displayed as "%C3%A4bc".

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
* install CUPS if necessary
* set up a new printer queue whose name contains non-ASCII characters with the following command (with root privileges):
  "lpadmin -p "äbc" -v http://example.org/printer3 -E"
* compile the class "PrintDialogTest" whose source code is given below:
  javac PrintDialogTest.java
* run the program:
  java PrintDialogTest
* click the arrow of the printer dropdown menu and look at the printer names

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
The printer name should be displayed as "äbc".
ACTUAL -
The printer name is displayed as "%C3%A4bc".

REPRODUCIBILITY :
This bug can be reproduced always.
