Hi together,
in May we had a discussion on this topic. Meanwhile I solved my problem
due to an other thread on this mailing list. Here is the code I use for
getting the printers and its tray names from OOo:

public class OOPrinter implements IPrinter {
/**

private static volatile IPrinter INSTANCE;
/**

*/
private XPrinterServer xPrinterServer = null;
/**
* Getting the instance of this class. This class is a
* singleton.
* @return [EMAIL PROTECTED] IPrinter} Instance of this class.
*/
public static IPrinter getInstance() {
if(INSTANCE == null)
synchronized (OOPrinter.class) {
if (INSTANCE == null) {
INSTANCE = new OOPrinter();
}
}
return INSTANCE;
}
/**

* OpenOffice.org does not offer a method to get the printer
* tray names directly. But is

*/
@Override
public String[] getPrinterTrays(String printerName) {
if(xPrinterServer == null)
initXPrinterServer();
XInfoPrinter xInfoPrinter =
xPrinterServer.createInfoPrinter(printerName);
// Print the trays received the OOo way
String ooTrays[] = xInfoPrinter.getFormDescriptions();
for(int i = 0; i < ooTrays.length; i++) {
String rangeRegex = "(.*;){2}[^;]{5,}";
Pattern pattern = Pattern.compile(rangeRegex);
Matcher matcher = pattern.matcher(ooTrays[i]);
while(matcher.find()){
String ooTray = matcher.group();
ooTrays[i] = ooTray.substring(
ooTray.lastIndexOf(";") + 1);
}
}
return ooTrays;
}
/**
* Getting the printer names from OpenOffice.org.
* @return String[] containing the printer names.
*/
@Override
public String[] getPrinters() {
if(xPrinterServer == null)
initXPrinterServer();
return xPrinterServer.getPrinterNames();
}
/**
* Initialising the [EMAIL PROTECTED] XPrinterServer}.
*/
private void initXPrinterServer() {
XComponentContext xCC =
OOWorkbench.getXComponentContext();
XMultiComponentFactory xMCF = xCC.getServiceManager();
Object oPrintServer = null;
try {
oPrintServer = xMCF.createInstanceWithContext(
"com.sun.star.awt.PrinterServer", xCC);
} catch (Exception e) {
e.printStackTrace();
}
try {
xPrinterServer = (XPrinterServer)
AnyConverter.toObject(
XPrinterServer.class, oPrintServer);
} catch (IllegalArgumentException e) {
e.printStackTrace();
}
}
}
-----%<-----
I hope this code serves you.
Greetings, Tobias
