What to Check When Your Printer Says It Is Offline But It Is Not
I needed to print a return label. One page. The printer said “Offline.” It was plugged in. The power light was on. My computer was connected to the same WiFi network. Everything looked fine except the little status message telling me the printer didn’t exist.
Twenty minutes of frustration later, it was working. Here’s what actually fixed it.
The first thing to try
Restart the printer. Unplug it, wait thirty seconds, plug it back in. Printers have tiny computers inside them. They get confused. Sometimes they just need to reboot like everything else.
This fixes about half of printer problems. If it works, stop here. If not, keep going.
The WiFi ghost connection
Printers often connect to your old WiFi network without telling you. If you changed your router or your WiFi password since setting up the printer, the printer is trying to join a network that doesn’t exist.
On most printers: go to Settings then Network then WiFi Setup. Look at what network it is connected to. If it is not your current network, reconnect it. You will need your WiFi password.
If your router has a 5GHz and 2.4GHz network with different names, make sure the printer is on the 2.4GHz one. Many printers don’t support 5GHz.
The IP address mismatch
Your router assigns addresses to devices. Sometimes the printer gets one address, your computer expects a different one, and nothing works.
Print a network configuration page from the printer’s settings menu. Look for the IP address section. On your computer, make sure the printer is using that exact address from the config page.
Windows: Settings, then Bluetooth and devices, then Printers. Right-click the printer and select Printer Properties. Click the Ports tab. The checked port should match the address on the config page.
The “Use Printer Offline” checkbox
Windows has a hidden checkbox called “Use Printer Offline.” When it is checked — and sometimes Windows checks it on its own after a failed print job — the printer shows as offline even when it isn’t.
Right-click the printer in Settings, then See what is printing. Click Printer in the menu bar, then uncheck “Use Printer Offline.”
I’ve fixed three friends’ printers just by unchecking this box. They thought I was a tech genius. I am not.
Quick Summary: Restart printer first. Check WiFi network — printers forget old networks. Print a network config page and match the IP address. Uncheck “Use Printer Offline” in Windows. Make sure printer is on 2.4GHz WiFi, not 5GHz.
