Apparently, the address \\prntsrv
was a DNS alias to \\prntserv
and the PrintServer
constructor was unable to deal with it. To get around this issue I used the following code (I could also use just the code in the catch block instead and it would work, but preferred not to):
try
{
// Create object to monitor the printer queue
PrintServer printServer = new PrintServer(serverPath);
mPrintQueue = printServer.GetPrintQueue(printerName);
}
catch (PrintServerException ex)
{
// If the problem might be creating the server because the name is an alias
if (ex.Message.Contains("printer name is invalid."))
{
string actualServerHostname = "\\\\" + Dns.GetHostEntry(serverPath.TrimStart('\\')).HostName;
// Create object to monitor the printer queue
PrintServer printServer = new PrintServer(actualServerHostname);
mPrintQueue = printServer.GetPrintQueue(printerName);
// Write to log about the use of a different address
}
else
{
throw;
}
}
