The mFax 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. 

To get started, you must first download and install the print driver.

We offer 2 versions of the Print to Fax driver for our reseller partners. Both versions are unbranded for white label use however one version includes a security certificate signed by Documo.

This means that users will be able to see the app was created by Documo. So, you have your choice between this version and one where there is no security certificate.

The latter may trigger a generic Windows security warning on installation. This is easily bypassed with a click on setup but you'll need to decide which version you'd like to use.

If you need to deploy the print driver for use in a Remote Desktop environment, click the button below to download the print driver for use for RDP/RDS.


Installation instructions:

Installing the print driver is simple and only take a few minutes.

At the end of the installation process you will be prompted to enter an Authorization Key. This key can be retrieved from the web portal in Settings > Your Settings under the API tab (see screenshot below)

Under PRINT DRIVER KEYS, type a name for the device you've installed the driver on (you can have multiple devices/keys) and click Generate. This will create a new key.

Next, click the Copy button to copy the key to your clipboard.

Lastly, paste the key into the field in the print driver setup screen and click Authenticate.

That's it. This will complete the setup of your Print to Fax driver.
