PrintServiceLookup is not working in Doppio

[santha6693]

PrintService[] printServices = PrintServiceLookup.lookupPrintServices(null, null);
System.out.println("Number of print services: " + printServices.length);
for (PrintService printer : printServices) {
System.out.println("Printer: " + printer.getName());
}
While Executing the above code the doppio through the following Exception.

java.lang.UnsatisfiedLinkError: Native method 'sun.print.CUPSPrinter.initIDs()Z' not implemented.

Looks like we need to stub some printer-related native methods to act as if no printers exist. I'll accept pull requests that implement these.

Even Printer is connected also the Exception is Throwing.

Can you please tell me how to send the text file to Printer using Doppio.

Doppio does not currently support printers, and we do not have plans to add support.

To add printer support, I imagine someone would need to write or compile a printer driver to JavaScript that produces postscript or a PDF, and instruct the browser to print it.

(I'm happy to accept any pull requests moving us in this direction, but cannot commit any resources to it myself.)
