POS Not Printing When the Internet Is Down?

If your POS stopped printing the moment the internet went down, your printer is almost certainly fine. Most cloud POS systems route print jobs through servers on the internet, so when your connection drops — or the POS company's servers go down — the ticket never reaches a printer that's sitting six feet away. Here's how to figure out what actually broke, what to do right now, and how to set things up so this never takes your kitchen down again.

First, find what actually failed (5 minutes)

Three different things can stop a receipt or kitchen ticket from printing: the printer itself, your in-store network, or the internet/cloud side. Each has a different fix, so check them in order.

Step 1 — Is the printer alive?

• Check the power light. No light: check the outlet and the power brick.
• Check for an error light or a blinking pattern. Open the cover, reseat the paper roll (shiny side out on thermal printers), close it firmly.
• Run a self-test: turn the printer off, hold the FEED button, turn it back on while holding. Almost every receipt printer will print a test page with its settings. If the test page prints, the printer is fine — move on.

Step 2 — Is your in-store network up?

• Look at your router and any network switches. Power lights on? Blinking activity lights?
• On the printer's self-test page, look for an IP address (a number like 192.168.1.240). No address, or 0.0.0.0, means the printer isn't getting on the network — check the Ethernet cable at both ends.
• If your POS terminal shows the printer as "offline" but the self-test printed and shows an IP address, the problem is between the POS and the printer — often a changed IP address (more on that in our kitchen printer setup guide).

Step 3 — Is it the internet or the cloud POS?

• Open a web page on your phone using the store Wi-Fi. Loads fine? Your internet is up — check your POS provider's status page (search "[your POS] status") because the outage may be on their end.
• Won't load? Your internet is down. Now the question is whether your POS can print without it — and for many cloud POS setups, the honest answer is "partly, and not the parts you'd expect."

This isn't rare: October 2025 and September 2023

On October 20, 2025, an Amazon Web Services outage in its us-east-1 region lasted roughly 15 hours and took down large parts of the internet — including Toast, one of the most widely used restaurant POS systems. Restaurant trade press documented "countless local restaurants using Toast" with complete system failures, and CNN quoted an owner who lost about a third of a day's business. Notably, Square publicly highlighted that it stayed up that day — POS vendors now market on outage resilience, which tells you how real the problem is.

Square has had its own turn: on September 7–8, 2023, an internal DNS error took Square down for roughly 18 hours. NBC News documented small-business owners losing thousands of dollars each while they couldn't take non-cash payments.

The lesson isn't "pick a different cloud POS." Every provider has incidents — Toast's own status page logs a steady drip of them. The lesson is that anything routed through the internet fails when the internet (or the provider) fails, and printing doesn't have to be one of those things.

What "offline mode" does and doesn't cover

Toast and Square both have offline modes, and they're genuinely worth setting up. But read the fine print:

• Payments: both can accept card payments offline by storing them and processing later when the connection returns. You carry the risk of declined cards processed after the fact.
• Ordering: order-taking on the terminal generally keeps working. Online ordering, delivery integrations, and anything that lives on someone else's server does not.
• Printing: this is the messy one. Whether tickets keep printing offline depends on how your print jobs are routed. If your terminal sends the job directly to a printer on your local network, printing can survive an internet outage. If jobs route through the vendor's cloud services or a cloud-connected hub, they stop. Toast maintains a whole support section on operating in offline mode — read it for your specific setup, and then test it by unplugging your modem on a slow afternoon. Don't find out during a Friday rush.

The fix that lasts: keep print jobs on your own network

Your printer and your POS terminal are usually in the same building, often on the same shelf. There is no technical reason a ticket needs to travel to a data center in Virginia and back to move six feet. The durable fix is architectural: make sure the path from POS to printer stays entirely on your local network (your "LAN" — the network inside your walls).

What that looks like in practice:

• Wired network printers, not cloud hubs. A receipt printer with an Ethernet jack, plugged into your switch, reachable at a fixed local address. Most POS software can talk to a standard network printer directly using a decades-old method called raw port 9100 printing — no internet involved.
• A stable local address for every printer. Tickets that vanish after a router reboot are usually an address change, not a hardware failure. Our kitchen printer setup guide walks through fixing addresses step by step.
• Local printing for USB-only printers. If you own a USB-only printer, you can put it on the network with a small adapter device instead of routing through a cloud service.

This is also the problem we're building ProxyNodes for. A ProxyNode is a small device (prototype stage — bench-proven, with pilot installs starting) that sits next to a printer and makes it look like a standard network printer to your POS, at an address that never changes, with everything staying on your LAN. If cloud outages have burned you and you're open to piloting early hardware, we'd like to talk.

Your outage survival checklist

Print this (while you can) and tape it inside a cabinet:

1. Know your offline mode. Enable it in your POS settings today; some systems require opt-in before the outage.
2. Test quarterly. Unplug the modem for ten minutes on a quiet day. Note what still works: payments? tickets? receipts?
3. Write down your printers' addresses. Run a self-test on each printer and keep the page. If a printer drops off, you can compare.
4. Keep a card imprinter or a "cash only" plan. The 2023 Square outage hurt most where owners had no fallback for payments.
5. Keep paper order pads. Handwritten tickets to the kitchen kept plenty of restaurants serving through the October 2025 outage.
6. Know your POS status page. Bookmark it on your phone (cell data works when store internet doesn't).
7. Fix the architecture when you can. Move printing onto your local network so the next cloud outage costs you online orders — not your whole kitchen.

If you're evaluating printers or a POS right now, it's worth understanding how the different printing protocols compare — some are local by design, some are cloud-dependent by design — and what your options are for using any printer with your POS. More operator guides live on our restaurants page.

FAQ

Frequently asked questions

Why does my POS stop printing when the internet goes down?

Many cloud POS systems send print jobs to their servers on the internet, which then send them back to your printer or a cloud-connected hub. When your connection or the vendor's servers go down, that route is cut — even though the printer itself is fine and sitting on the same network as your terminal.

Does Toast offline mode keep printing?

Partly, and it depends on your setup. Order-taking and stored card payments generally work offline, but whether tickets print depends on how your print routing is configured. Toast has a dedicated support section on offline mode — read it for your hardware, then test by disconnecting your internet during a quiet hour.

Can my kitchen printer work with no internet at all?

Yes, if the print job travels only over your local network — POS terminal to printer, inside your walls. Wired network printers reached directly by the POS keep printing during internet outages. Anything routed through a cloud service does not.

How long do POS outages actually last?

The two biggest recent ones: the AWS outage of October 20, 2025 ran about 15 hours and took down Toast-dependent restaurants, and the Square outage of September 7-8, 2023 ran about 18 hours. Smaller incidents of minutes to hours happen far more often.

Is this a reason to switch POS providers?

Usually not by itself. Every cloud POS has outages, and switching costs are real. The higher-leverage move is making your in-store printing independent of the internet, so a vendor outage costs you online ordering instead of your entire kitchen.
