How to Send a Fax Using Print to Fax

The Print to Fax feature lets you send a fax directly from any application on your computer — just like printing to a regular printer. Once installed, a virtual "Send as Fax (Fax.Plus)" printer appears in your print dialog, letting you fax documents from Word, Adobe Acrobat, your browser, or any other app without saving or uploading files manually.

Step 1: Download and install the Print to Fax driver

1. Log in to your Fax.Plus account.
2. Go to Settings → Faxing.
3. Scroll down to the Send Fax from Email & Desktop section.
4. Under Print to Fax, click Download and select your operating system:
   • Download for Windows
   • Download for macOS

5. Open the downloaded file and follow the on-screen installation instructions.

   Note: You may need administrator permissions on your computer to install the driver.

6. Once the installation is complete, sign in to your Fax.Plus account to begin using the Print to Fax feature. You may be prompted to grant additional permissions for the feature to function properly.
7. After a successful login, you will see a “Login successful, you can close this tab” message.

Step 2: Send a fax from any application

1. Open the document you want to fax (PDF, Word file, web page, etc.).
2. Open the Print dialog - usually via File → Print or Ctrl+P / Cmd+P.
3. In the Printer dropdown, select Send as Fax (Fax.Plus).
4. Click Print.
   
5. A Fax.Plus window will open - enter the recipient's fax number and any additional details.
6. Confirm and Send.

Configuring Print to Fax settings

Once the driver is installed, you can adjust its settings directly from the Fax.Plus Print to Fax app.

1. Open the Fax.Plus desktop app on your computer.
2. You will see your account name displayed at the top (e.g. "Signed as John Smith").
3. Click Settings in the top-right corner of the app.
4. Under Send faxes with..., choose your preferred method from the dropdown:
   • Browser — clicking Print opens the fax sending flow in your web browser.
   • Desktop App — the fax sending flow opens directly within the desktop app.
5. Click Save to apply your changes.
