IIS7 The printer name is invalid.

Have tried countless remedies listed here and in other forums with no avail. Most of those threads are years old.

Using IIS7 on Windows Server 2008R2, client is Win8. Both 64bit Correct printer drivers loaded on both.

Can reach the print server site: https://XX.XX.XX.XX:XX/Printers/printername/.printer

But when I try and connect using the link under Printer Actions I get the following error

Printer Installation Failed

The printer name is invalid.

I've tried opening ports 443, 631, and even tried some custom ports. Client has firewall off.
