A printer IP address is a unique number that identifies your printer on your network, so your computer knows where to send documents to print

Think of it like a mailing address for your printer. When you hit print on your computer, that document has to travel somewhere — it needs to know which device on your home or office network is the printer. The IP address is how your computer finds it. Without one, your computer wouldn't know whether to send the job to your printer, your router, your phone, or your neighbour's device.

IP stands for Internet Protocol. Every device that connects to a network — your laptop, phone, printer, security camera, smart speaker — gets one. On a home network, these addresses are usually assigned automatically by your router. On a work network, they might be assigned by an IT department or a system called DHCP (Dynamic Host Configuration Protocol), which hands out addresses like a parking lot attendant assigning spaces.

Key Takeaways

  • An IP address is a unique number that lets your computer locate and communicate with your printer over the network.
  • Home printers usually get their IP address automatically from your router, and you rarely need to know what it is.
  • If your printer stops printing, finding its IP address can help you troubleshoot the connection or reinstall the printer.
  • IP addresses on home networks typically look like 192.168.1.100 — four groups of numbers separated by periods.
  • A printer can have both a local IP address (for your home or office network) and a cloud address (if it supports remote printing).

How your printer gets an IP address

When you first turn on a printer connected to your WiFi or plugged into your network with an ethernet cable, your router automatically assigns it an IP address. This happens without you doing anything. The printer asks the router "what address should I use?" and the router hands one out, usually from a pool of addresses it keeps reserved for devices.

This automatic assignment is called DHCP, and it's the default for almost all home and small office networks. The address can change over time — if you restart your printer or it disconnects and reconnects, it might get a different one. That's usually fine, because your computer and printer re-find each other automatically.

Some printers also let you set a static IP address, meaning the same address every time. This is more common in offices where IT staff want to control which devices have which addresses. For a home printer, it's rarely necessary.

What an IP address looks like

A typical IP address on a home network looks like this: 192.168.1.100. It's four groups of numbers, each between 0 and 255, separated by periods. The first three groups usually stay the same on your home network (192.168.1 in this example), and the last group changes for each device. So your computer might be 192.168.1.5, your printer 192.168.1.100, and your phone 192.168.1.50.

The first three groups are determined by your router's settings. Most home routers use 192.168.1.x or 192.168.0.x by default, but some use different ranges. The important thing to know is that all devices on your network share the same first three groups — that's how they know they're on the same network.

When you actually need to know your printer's IP address

Most of the time, you don't need to know it. You add your printer to your computer once, and the operating system remembers it. When you print, your computer finds it automatically.

You might need to find the IP address if your printer stops working and you want to troubleshoot. Some printers have a small screen on the front that displays the address. Others print a configuration page if you hold down a button. You can also find it by logging into your router's settings and looking at the list of connected devices — most routers show you the name and IP address of everything attached.

Another reason to know the address: if you want to access your printer's settings from a web browser. Many printers let you type the IP address into your browser (like typing 192.168.1.100 into the address bar) to see ink levels, change WiFi settings, or update firmware. This is usually optional — you can do most of these things through the printer's own buttons or through software on your computer — but it's an option if you prefer the web interface.

IP addresses and printer security

Your printer's IP address is only useful to devices on your own network. If you're on a home WiFi network, other people on that same network can see your printer's address, but people outside your home cannot. Your router acts as a barrier.

That said, printers are sometimes overlooked when people think about network security. If your printer has a web interface (the settings page you access through a browser), it might have a default password that you never changed. If someone gets on your WiFi network, they could potentially access that interface. Most home users don't need to worry about this, but if you're concerned, check your printer's manual for how to set a password for the web interface.

Cloud printing and multiple addresses

Some modern printers support cloud printing, which means you can send a document to print from anywhere — not just from your home network. Google Cloud Print (now retired) and similar services work by giving your printer a second address on the internet, separate from its local IP address on your home network.

If your printer supports cloud printing, it still has a local IP address (192.168.1.100 or similar) for printing at home. But it also registers with a cloud service, which gives it a way to receive print jobs from outside your home. You don't need to know either address — the cloud service handles the routing. You just select "print to cloud" and choose your printer by name.

Finding your printer's IP address if you need it

The easiest method depends on your printer model. Check the printer's front panel first — many have a small screen or a button that prints a configuration page showing the IP address. If your printer doesn't have a screen, look for a button labeled "info" or "settings" and hold it down for a few seconds.

If that doesn't work, log into your router's settings. Open a web browser and type 192.168.1.1 or 192.168.0.1 (whichever is your router's address — check the back of the router or your manual). Log in with your router's username and password. Look for a section called "connected devices" or "DHCP clients." Your printer should be listed there with its IP address.

On Windows, you can also open Settings, go to Devices, then Printers and Scanners, click your printer, and select "Printer Properties." Some printers show the IP address there. On Mac, go to System Preferences, Printers and Scanners, select your printer, and click "Supply Levels" or "Options and Supplies" — the IP address is sometimes listed there.

Frequently Asked Questions

Can I change my printer's IP address?

Yes, but you usually shouldn't. Most home printers get their address automatically from the router, and changing it manually requires accessing the printer's settings through a web browser or control panel. If you do change it, your computer might not find the printer automatically anymore. If you need a static address for a specific reason, your printer's manual will explain how.

What if my printer has the same IP address as another device?

This shouldn't happen on a properly functioning network — your router is designed to prevent it. If it does happen, restart both devices. The router will reassign addresses. If the problem persists, restart your router itself by unplugging it for 30 seconds.

Does my printer need to be on the internet to have an IP address?

No. An IP address is just for your local network. Your printer can have an IP address and work perfectly fine without ever connecting to the broader internet. It only needs to be on your home or office WiFi network, or connected via ethernet cable to your router.

Is it safe to share my printer's IP address with someone?

It's safe to share with someone on your own network — they already know it if they're connected to your WiFi. Sharing it with someone outside your network is harmless, since they can't reach it anyway. Your router's firewall prevents outside access to devices on your local network.
