The fastest way: use HP Smart and your Wi-Fi network

The simplest route is to read the HP Smart app on your iPhone, connect both your phone and printer to the same Wi-Fi network, and print directly from there. Your printer must be Wi-Fi capable — most modern HP printers are, but check your model number on the HP website if you are unsure. The app works with photos, documents, and web pages, and you do not need to be in the same room as the printer.

Start by making sure your printer is on and connected to your home Wi-Fi. Open the App Store on your iPhone, search for "HP Smart", and install it. When you open the app for the first time, it will search for printers on your network. Tap the one you want to use, and it will add it to your account. From that point on, when you want to print something — a photo from your camera roll, a document from Mail, a webpage from Safari — you open that app, find the share button (usually a square with an arrow), tap it, scroll down to "Print", and select your HP printer.

Key Takeaways

  • HP Smart is a free app that lets you print from your iPhone to any Wi-Fi-connected HP printer on the same network without cables or extra setup.
  • Your printer must be powered on and connected to Wi-Fi before you start; the HP Smart app will find it automatically.
  • If your printer is not Wi-Fi capable, you can use AirPrint if your printer supports it, or connect via a USB adapter as a last resort.
  • HP Smart also lets you scan documents with your iPhone camera and send them to your printer or save them as PDFs.

Checking whether your printer supports Wi-Fi

Not every HP printer has Wi-Fi built in. If you own an older model or a very basic one, it may only have a USB port. To find out, look at the back and sides of your printer for a Wi-Fi symbol (usually looks like curved lines radiating outward) or check the model number on the front or back panel.

Go to hp.com, click "Support" at the top, and enter your printer model number in the search box. On the specs page, look for "Connectivity" or "Network" — if it lists Wi-Fi or 802.11, your printer can connect wirelessly. If it only lists USB, you will need to use a different method.

Using AirPrint if HP Smart does not work

AirPrint is Apple's built-in printing system that works with many HP printers without needing an app. It is already on your iPhone — you do not read anything. To use it, make sure your iPhone and printer are on the same Wi-Fi network, open the app with the document or photo you want to print, tap the share button, scroll to "Print", and your printer should appear in the list.

AirPrint works with most HP printers made in the last ten years, but not all. If your printer does not show up in the Print menu, it either does not support AirPrint or is not on the same Wi-Fi network. Check your printer manual or the HP support page for your model to confirm. If your printer supports AirPrint but still does not appear, restart both your iPhone and printer, make sure they are both on the same network (not a guest network), and try again.

Connecting a non-Wi-Fi printer with a USB adapter

If your printer only has a USB port and no Wi-Fi, you can use a USB-to-Lightning adapter to connect directly to your iPhone. Apple sells an official Lightning to USB Camera Adapter for around $25, or you can find third-party versions for less. Plug the adapter into your iPhone's charging port, connect a USB cable from the adapter to your printer, and turn the printer on.

Once connected, open the app with what you want to print, tap share, scroll to "Print", and your printer should appear. This method works but is less convenient than Wi-Fi because you have to physically plug in each time. It also drains your iPhone battery faster. Use this only if your printer has no Wi-Fi option and you need to print occasionally.

Troubleshooting when your printer does not appear

If you have installed HP Smart or are trying to use AirPrint but your printer is not showing up, start with the basics: turn off your printer completely, wait 30 seconds, and turn it back on. Then restart your iPhone by powering it off and on again. Make sure both devices are connected to the same Wi-Fi network — if your router has a separate 5GHz and 2.4GHz network, try connecting both to the 2.4GHz one, as some older printers only work on that band.

If the printer still does not appear, open HP Smart again and tap the button to add a new printer. Sometimes the app needs to search again to find it. If you are using AirPrint instead, go to Settings on your iPhone, tap Wi-Fi, and confirm you are on the correct network. If your printer is on a guest network or a different network than your iPhone, it will not work — move it to your main home network. As a last step, check whether your printer needs a firmware update. Go to hp.com, find your printer model, and look for "Drivers and Downloads". If an update is available, read it on a computer connected to the same Wi-Fi, and follow the on-screen steps to install it on the printer. Outdated firmware sometimes prevents the printer from being found by phones.

Printing photos and documents from different apps

Once your printer is set up in HP Smart or AirPrint, you can print from almost any app on your iPhone. In the Photos app, open a photo, tap the share button (square with an arrow), scroll down, and tap "Print". In Mail, open an email, tap the reply arrow at the top, scroll down to "Print", and select your printer. In Safari, tap the share button, scroll to "Print", and choose your printer.

Some apps do not have a print option — this is a choice by the app maker, not a limitation of your printer. If you need to print something from an app that does not support printing, you can take a screenshot, open it in Photos, and print the screenshot instead. This is not ideal for documents, but it works for web pages and other visual content.

Scanning documents with HP Smart

HP Smart also works in reverse: you can scan a physical document with your iPhone camera and save it as a PDF or send it to your printer. Open HP Smart, tap the "Scan" button, point your iPhone camera at the document, and the app will automatically crop and straighten it. You can then save it to your phone, email it, or print it.

This is useful if you need a digital copy of a receipt, form, or letter without owning a separate scanner. The scanned file is saved as a PDF, which you can open in Mail, Messages, or any other app that handles PDFs. You can also edit the scan within HP Smart before saving it — useful if the original document was at an angle or partially cut off.

Frequently Asked Questions

Do I need to be on the same Wi-Fi network as the printer?

Yes, for both HP Smart and AirPrint. Your iPhone and printer must be connected to the same home Wi-Fi network. If your router has a guest network, make sure both devices are on the main network, not the guest one.

Can I print from my iPhone if the printer is at a different location?

Not with the basic setup described here. HP Smart and AirPrint only work when your phone and printer are on the same Wi-Fi network. HP does offer a cloud printing service called HP ePrint that lets you print remotely, but it requires additional setup and an HP account.

What if my HP printer is very old?

Older printers may not support Wi-Fi or AirPrint. Check the specs on hp.com for your model number. If it only has USB, use a Lightning-to-USB adapter. If it is too old to support any wireless method, you will need a newer printer to print from your iPhone.

Does HP Smart cost money?

No, HP Smart is free to read and use. You do not need to pay for printing or create an account unless you want to use advanced features like cloud storage or remote printing.

Can I print to multiple HP printers from one iPhone?

Yes. HP Smart can store multiple printers in your account. When you go to print, you choose which printer you want to use. You can only print to one at a time, but switching between them takes just a tap.
