how to lookup network printers

I'm not looking to get printers that are installed on the local system, I'm looking at finding printers within the network. I've tried the following:

AttributeSet aset = new HashAttributeSet();
aset.add(new PrinterName("\\\\PRINT_SERVER\\PRINTER_NAME", null));
PrintService service[] = PrintServiceLookup.lookupPrintServices(null, aset);

But this only gets me the local printers isntalled on the machine that the code is running on. What i'm looking for is to get other network printers, by name, from across the network.

Any help would be greatly appreciated.

Try passing null for both parameters

passing null for both parameters will just bring you back a listing of all seen printers installed on the server running the code.  I'm looking to get access to printers across the network through code without having to add the printers to the local machine first.  As there are a number of printers at multiple locations throughout the network.

Have you tried using attribute PrinterURI ?

Could you give me an example of the PrinterURI with the code example I provided?

Personally i've never constructed one, but this might help

Do you know where you to download and install the gnu package they are using within the source code you sent?

java doesn't provide a standard way to discover all network printers.

You might be better off trying a different approach with discovery, such as something Active Directory based, since it looks like you have a Windows network

mainly it's windows based but the server the code is on is linux and being built in java.   I'm finding that java doesn't provide a standard way to discover all network printers but is there 3rd party packages i could install that would help out with this process?    I also read somewhere where someone used that IppPrintService and it worked for them, so I'm at least going to give it a shot

no it doesn't as I mentioned above. you can use 3rd party stuff but it depends on the protocol that the printers are being shared with. for example the gnu code for ipp

If you have various OSs it's going to be more difficult still. You could perhaps look for services running on the IPP port (631). That would take care of the Linux networks

why?

how will that help?

There's an old API on Sourceforge called 'jipsi' for IPP. It works for me for discovering IPP services
