When attempting to add an IPP printer to a Windows Vista or Windows 7 workstation over HTTPS, the queue may fail to install with the following error:
Connect to Printer
Windows couldn't connect to the printer. Check the printer name and try again. If this is a network printer, make sure that the printer is turned on, and that the printer address is correct.
This can be resolved by either:
- Configuring the print server to use a valid SSL certificate from an external certificate authority trusted by the workstation
- If both the print server and the workstation are in the same domain, configuring the print server to use a valid SSL certificate from an enterprise certificate authority
- If the print server is using a self-signed certificate, installing the self-signed certificate on the workstation
How to Install an IPP Print Server's Self-Signed Certificate on a Windows Client
If your print server is using self-signed certificates, the following steps can be used to install the self-signed certificate on the client(s) so they are able to use the printer. Note: this should only be performed for SSL certificates from servers you trust.
- Log on to the client as an administrator
- Find Internet Explorer in the start menu, right click on it, and click Run as administrator
- In Internet Explorer, browse to the Print Server using HTTPS (e.g. https://PrintServerName/)
- In the address bar, the words "Certificate Error" should appear on the right side next to a Red shield icon - click on the error
- Click "View Certificates"
- On the certificate window, click "Install Certificate..."
- Select "Place all certificates in the following store"
- Click "Browse..."
- Select "Trusted Root Certification Authorities" and click OK
- Click Next, then click Finish
- A security warning will appear that you are adding a certificate from a source that cannot be validated. Click Yes to trust this SSL certificate.
- Close Internet Explorer
- The printer can now be installed
