What is print to fax?

Print to fax is a feature that lets you send a document to a fax machine the same way you print it: you choose a fax printer in the Print dialog, and instead of putting ink on paper, a driver hands the pages to a fax modem or fax server that transmits them. It was the standard way offices faxed from their desktops before online services took over. This fax-from-computer.com guide explains how the classic setup worked, where print2fax systems still survive, and the modern two-step equivalent anyone can use.

How the print and fax driver worked

The trick behind print to fax is a virtual printer: a driver that looks like any other printer to your applications but produces a fax transmission instead of a physical page. When you printed to it, a dialog asked for the recipient's fax number, rendered the document into fax format, and queued the job.

Where the fax actually left the building varied. Small offices used a fax modem inside the PC on an ordinary phone line; bigger ones ran a fax server, a central machine with a bank of phone lines that every desk could print to.

Where print2fax still appears

You will still meet print2fax drivers in businesses that run legacy fax servers: medical practices, law firms, logistics companies and government offices. If your work PC shows a printer simply named Fax in the Print dialog, you are probably looking at one. These systems keep working as long as the server and its phone lines are maintained, which is exactly the overhead that pushes organizations toward cloud faxing.

The built-in Windows version

Windows still ships a minimal version of the idea: Windows Fax and Scan installs a Fax printer you can print to from any application. The constraint is unchanged from the 1990s, though. It only transmits if the PC has a fax modem connected to an analog phone line, which almost no modern computer does.

The modern equivalent: print to PDF, then fax online

Today the virtual printer that matters is Print to PDF. Pair it with a browser fax service and you have rebuilt print to fax without a modem, a server or a phone line. It is the workflow we use ourselves at fax-from-computer.com.

  1. In any application, choose Print and select Microsoft Print to PDF, or use Save as PDF on a Mac.
  2. Open FaxToFax.com in your browser and sign in; new users sign up with an email and a one-time code.
  3. Upload the PDF, enter the recipient's fax number, and send, or schedule the fax up to 90 days ahead.
  4. Check the status and keep the time-stamped delivery receipt once it shows Delivered.

Why the online version wins

The two-step workflow is not just a workaround; it fixes the weak points of the original.

  • No hardware to maintain: no modem, no server and no dedicated phone lines.
  • Proof of delivery: each delivered fax carries a time-stamped receipt, and failed attempts do not use plan pages.
  • Security: documents travel over TLS 1.2 or newer and sit encrypted at rest, backed by an append-only audit log.
  • It works from anywhere: any computer or phone browser, not just the desk wired to the fax server.
FAQ

What Is Print to Fax? How It Works and What Replaced It: questions

What does print to fax mean?

It means sending a document to a fax recipient through the Print dialog: a virtual fax printer driver captures the print job and transmits it through a fax modem or fax server instead of printing it on paper.

What is print2fax?

Print2fax is a common name for the virtual printer driver supplied with office fax servers. Printing to it prompts for a fax number and queues the document for transmission over the server's phone lines.

Can I still print and fax from Windows?

Only with Windows Fax and Scan plus a fax modem and an analog phone line. Without that hardware, print the document to PDF instead and send the file through an online fax service.

Do I need special software for print to fax today?

No. Every modern system can print to PDF, and a browser-based service like FaxToFax.com handles the transmission. There is nothing to install, and the process is identical on Windows and Mac.

Is print to fax the same as scan to fax?

No. Print to fax starts from a digital document on your computer, while scan to fax starts from paper on an all-in-one machine. Both end the same way, with the pages transmitted to the recipient's fax number.
