Hi Legends.  I'm hoping to pick your brains and get some help.

I'm working at a site where there is a iPrint deployment using short printer name  (eg  \\Site\AA123456-p6 ) as the installed printer names.

When we select this printer name  and try to print within our application/test tool written in DotNet we get a generated error stating that the printer name is invalid.  the FQDN port ipp://iPrint.Server.FQDN.com/iprint/AA123456-p6 does resolve and i can browse via the HTTP address.  The short name \\Site does not resolve by ping or DNS nslookup on the host system
no matter what I do or configure I cannot get this printer to work.

The only threads and info I can find about this are 10 or more years old and don't seem to address my issue.

The code for our test tool is as follow;

private static System.Printing.PrintServer GetPrintServer(string servername)
 {
 System.Printing.PrintServer ps = null;
 if (string.IsNullOrEmpty(servername))
 {
 // local printer name
 ps = new System.Printing.LocalPrintServer();
 }
 else
 {
 // network printer share
 ps = new System.Printing.PrintServer(servername);
 }
 return ps;
 }

public static System.Printing.PrintQueue GetPrintQueue(string printServer, string printQueue)
 {
 System.Printing.PrintQueue pq = null;
 System.Printing.PrintServer ps = GetPrintServer(printServer);
 if (ps != null)
 pq = ps.GetPrintQueue(printQueue);
 return pq;
 }

When we try to resolve the short name it fails.  Are we missing something when trying to call GetPrinterServer?
'Print and Document service' is installed.
Test tool is here: https://drive.google.com/file/d/1746kgmWbCIchqxkBZqjP5RDZrN7QhVXC/view?usp=sharing if you have a similar site and can try to replicate?

Any help is really appreciated!
