How to Send a Fax from Printer (and What to Do if You Don't Have One)
Published · www.ronfax.com
Learn how multifunction printers send faxes—and how to skip the printer entirely with phone-to-PDF uploads and RonFax for instant online transmission.
Searches for how to send a fax from printer spiked 100% year over year in Google Trends—usually because someone is staring at an office multifunction device (MFP) and does not know which touchscreen menu to trust, or because the fax line was disconnected when they switched internet providers.
This article explains how printer-based faxing is supposed to work, when it fails, and what to do when you do not have a working printer-fax at all (spoiler: your phone plus RonFax is enough).
How a "fax from printer" is supposed to work
Most business-class printers combine scan + print + fax. If an analog phone line is plugged into the correct port and the line supports fax tones, you can:
- Place the document on the flatbed or ADF
- Enter the destination fax number on the panel
- Press Send or Start
If that sounds simple, reality is messier: wrong jacks, VoIP adapters that clip fax signals, and drivers that quietly fail without an obvious error.
When your printer cannot fax
You might see failures if:
- Your home uses VoIP-only voice (many fiber and cable bundles)
- The RJ-11 line was never connected or was removed
- The MFP's fax license expired (common on leased office copiers)
- You are mobile and the printer is two towns away
When any of these happen, stop fighting hardware. You only need a clear PDF of each page.
What to do if you don't have a printer or working fax line
Option A — Scan with your phone
Modern iPhones and Android phones produce sharp PDFs. Lay the page on a flat surface, use good light, and export a single multi-page PDF when possible.
Option B — Use a file already on your computer
If the document originated as PDF or Word, export or print to PDF. That file is ready for online fax.
Option C — RonFax online transmission
RonFax turns a PDF into a real fax transmission over the US phone network:
- Upload PDF — drag and drop or pick from your phone
- Enter the fax number — we format US numbers automatically
- Pay and send — one-time checkout; track delivery on a status page
No hardware, no phone cord, no subscription. That is the practical answer to how to send a fax from printer when your printer is not cooperating.
