A DESCRIPTION OF THE PROBLEM :
There were some reports of PrintServices being incorrectly listed as "not accepting jobs" with recent versions of CUPS (e.g. in the comments of bug #6181488).

I was experiencing this as well and can confirm the following: it does no longer occur when the Java VM ist started with LANG=C.

Since the output of lpc status is localized according to the LANG setting supports the suggestion that this is indeed a parsing problem as suggested in the discussion.

With LANG=de_DE, my version of lpc status reads something like:
cos1:
        Drucker verbunden über 'ipp' Geschwindigkeit -1
        Warteschlange ist freigegeben
        Drucken ist freigegeben
        Keine Einträge
        Dienst läuft

With LANG=C, it reads:
cos1:
        printer is on device 'ipp' speed -1
        queuing is enabled
        printing is enabled
        no entries
        daemon present


STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
With CUPS 1.2.4 installed, compile the test program below and run

LANG=de_DE java PrintTest
LANG=C java PrintTest

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
It is expected that the test program returns the same result when run with LANG=de_DE and with LANG=C
ACTUAL -
$ LANG=de_DE java PrintTest
Name: cos1 not-accepting-jobs
Name: cos2 not-accepting-jobs
...
$ LANG=C java PrintTest
Name: cos1 accepting-jobs
Name: cos2 accepting-jobs
...

REPRODUCIBILITY :
This bug can be reproduced always.

---------- BEGIN SOURCE ----------
import javax.print.PrintService;
import javax.print.PrintServiceLookup;
import javax.print.attribute.standard.PrinterIsAcceptingJobs;


public class PrintTest {

public static void main(String[] args) throws Exception{

PrintTest test = new PrintTest();
test.list();
}

private void list() {
PrintService[] services =
PrintServiceLookup.lookupPrintServices(null, null);

PrintService s = null;
for (PrintService service : services) {
System.out.println("Name: "+service.getName() + " " +
service.getAttributes().get(PrinterIsAcceptingJobs.class));
}

}
}

---------- END SOURCE ----------

CUSTOMER SUBMITTED WORKAROUND :
Setting LANG=C, although this it not feasable in our case, since all Java ressources are not localized anymore as well.
