Windows printing Printing Needs an admin

0x00000709: the printer name is invalid

Likely causes

  • A typo or old name in the printer path, such as \\server\printer.
  • The printer was renamed or removed on the print server.
  • The print server is reached through a DNS alias (CNAME), and a non-Microsoft DNS service answers in a way Windows doesn't handle.
  • The client can't talk to the print server over the network.

How to fix it

  1. Check the exact share name on the print server and re-add the printer using \\servername\sharename.
  2. Try the server’s real host name instead of an alias. If that works, the alias is the problem.
  3. Admins using a CNAME with third-party DNS: Microsoft’s workaround is to set the DnsOnWire registry value on the print server, add the alias as a NetBIOS name in the server’s hosts file, and restart the Print Spooler service.
  4. On Windows 11 22H2 and later, print connections use RPC over TCP by default. Admins should make sure the firewall allows TCP 135 and the dynamic RPC ports (49152 to 65535) to the print server.
