FULL PRODUCT VERSION :
1.7.0_55

ADDITIONAL OS VERSION INFORMATION :
Windows version 6.1.7600

EXTRA RELEVANT SYSTEM CONFIGURATION :
Printing to a printer with temporary connection problems

A DESCRIPTION OF THE PROBLEM :
When an applet tries to print using jnlp everything goes well if the printer has no error. But when a a previous print job is hangng on the printer because of some connection problem, the applet receives a UnavailableServiceException in ServiceManager.lookup("javax.jnlp.PrintService"), and so it's unable to spool the print job. 

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
PrintService ps = (PrintService) ServiceManager	.lookup("javax.jnlp.PrintService");
 // Throws Exception when previous print job is in error
ps.print(this));

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
The printer is configured and accepting jobs in other windows software. The applet should get the same behavior and should be able to send new jobs to the print spooler.
ACTUAL -
The applet can't get a PrintService to spool the print job. Instead it gets a UnavailableServceException when doing ServiceManager.lookup()

ERROR MESSAGES/STACK TRACES THAT OCCUR :
No error. Just an exception thrown.

REPRODUCIBILITY :
This bug can be reproduced always.

CUSTOMER SUBMITTED WORKAROUND :
No workaround. It's annoying for the user. Compares badly with windows native software.
