The Zenith Print to Fax driver is a simple Windows application that allows you to send a fax from any Windows program that allows you to print.
Before installing the driver, you will need to create an API Key. This key can be created from the web portal in Settings > API Keys (see screenshots below). Click the Create button:
Type a name for the API key. I’ve used “Print Driver” below. Select “Print Driver” from the “Access Level” pulldown menu and click Create. This will create a new token.
Next, click the Copy button to copy the token to your clipboard.
Download and install the print driver. Finally, paste the key into the field in the print driver setup screen and click Authenticate.
