Set Up Faxing From Your Computer: Software and Drivers

What you need for computer faxing

Computer faxing starts with the hardware. Your printer must have a fax modem and a way to connect to a telephone line. Not all printers include fax; most all-in-one models do, but single-function printers usually do not. If your machine has a fax function, it will have an RJ-11 phone port labeled LINE and possibly EXT. Confirm this before buying, or check the best fax printers guide.

You also need a fax driver or software. Many operating systems list the printer as a fax device once the driver is installed. On Windows, the fax driver appears as a separate queue; on macOS, you may need to enable the fax-only option in the printer settings.

Check fax support and phone connection

Before configuring software, test the fax hardware. Connect the printer to a wall jack using a telephone cable. The printer's display should show a fax setup menu. Some models require you to enter your country and company header. If there is no fax menu, the printer may not have fax capability, or the fax module is optional.

Your phone line should provide a dial tone. Most fax machines use the same analog line as a landline phone. Voice over IP services may not be compatible unless the service supports fax transmissions. Contact your provider if you have trouble receiving a dial tone at the fax port.

Install the fax driver on Windows

On Windows, you can add a printer using the built-in setup. For modern devices, Windows supports Mopria certified printers, which means you can print without a vendor-specific driver. However, faxing is not always part of the standard driver. Many manufacturers provide a separate fax driver or a full feature driver from their support page. Download the driver from the maker's site, run the installer, and select the fax option when prompted.

If you are using a printer that supports IPP Everywhere, Windows can also discover it automatically without extra software. IPP Everywhere is a PWG standard that allows personal computers and mobile devices to find and print without vendor-specific software. This can include fax features if the device exposes them. Check the printer driver languages guide for details, but for fax, a full driver is usually safer.

Install the fax driver on macOS

macOS includes built-in drivers for many printers, and it also supports IPP Everywhere for driverless setup. When you add a printer in System Settings, choose the device from the list; macOS will create a print queue. Some multifunction printers appear with a separate fax queue. If not, you may need the manufacturer's driver and utility to expose the fax function.

After installation, open System Settings > Printers & Scanners, select the printer, and look for an option to set up fax receiving. macOS can also send faxes through the print dialog if the driver supports it. If you do not see a fax option, the driver may not include fax support, or the printer's fax module is not enabled.

Configure the fax driver

Once the driver is installed, configure your fax identity. This includes your fax number, company name, and the number of rings before answering for incoming faxes. These settings are usually in the printer's control panel or in the driver's properties. On Windows, open Devices and Printers, right-click the fax queue, and go to Printing Preferences.

Your computer may also have a built-in fax program. Windows Fax and Scan is available in most Windows versions; it lets you compose a cover page and send a fax using a modem or a network fax device. On macOS, you can use the Fax option in the Print dialog to send a file as a fax.

Send a fax from a document

The simplest way to fax a file is to open the document and choose Print. Select the fax driver from the printer list, enter the recipient's number, and confirm. The fax driver converts the file to a faxable format and uses the printer's modem to dial and transmit. You can also attach scanned documents if your printer has a scanner.

For multiple faxes, use the printer's PC-FAX utility if provided. These tools often include an address book and a sending history. The exact steps vary, but the general flow is the same: select the recipient, attach the file, and send.

Use the printer's software vs. OS built-in

Some printers come with a full feature application that bundles print, scan, and fax in one interface. This is convenient if you need to manage a phonebook or scan-to-fax tasks. The downside is that you must install that vendor software. On the other hand, the operating system's built-in tools are lightweight and avoid extra drivers, but they may not expose every fax option.

For businesses, dedicated fax software can add features like secure release or logging. However, for occasional home use, the built-in Windows Fax and Scan or macOS fax option is often enough. If your printer is ENERGY STAR certified, using its power management features can also reduce energy while idle, but that is separate from fax setup.

Troubleshooting and best practices

If the fax fails, first confirm the phone line is live and that the printer is connected to the wall jack, not to a phone extension that is off the hook. Then check the printer's error log or fax activity report. Many printers have a fax test function in the setup menu. Also ensure that the fax driver is set as the default if you are using a print-to-fax workflow.

If you do not have a landline, consider an online fax service that works through email. That is a separate path, but our all-in-one fax specs page explains what to look for in a fax-capable device. Keep the printer's firmware updated; manufacturers often improve fax compatibility with updates.

What to pick for your use

Questions

Do I need a phone line to fax from my computer?

Yes, you need an analog phone line connected to the printer's fax port. The printer uses the line to dial and transmit the fax.

Can I send a fax from my printer without installing any software?

Possibly, if the printer supports IPP Everywhere and your operating system includes built-in fax support. However, most users need a full driver to access fax features like address books and sending logs.

Is there a separate fax driver for Windows?

Many manufacturers provide a separate PC-FAX driver or include fax support in the full feature driver. Check the maker's support page for the model-specific driver.

Why does my Mac not show a fax option?

The printer driver may not include fax support, or the fax module is disabled in the printer settings. Install the manufacturer's full driver and verify the printer's fax setup menu.

Can I receive faxes on my computer?

Yes, some fax software lets you receive faxes and save them as PDF files. Your printer must be connected to a phone line and configured to answer incoming calls.

What if I have a VoIP phone service?

VoIP may not be compatible because faxing relies on analog signals. A traditional landline is recommended for reliable fax operation.
