The basic steps: what happens when you scan
Most modern printers have a built-in scanner. To send a scanned document to your computer, you place the paper in the printer's document feeder or on the glass bed, press the scan button on the printer itself, and the printer sends the image file to your computer over your home network or USB cable. The file usually lands in a folder on your computer called "Scans" or "Documents" — the exact location depends on your printer model and how you set it up.
The process works differently depending on whether your printer connects to your computer by USB cable or over WiFi. USB is simpler to set up but requires the cable to stay plugged in. WiFi lets you scan from anywhere in your home but requires both devices to be on the same network.
Key Takeaways
- Most printers have a physical scan button on the device itself — press it after loading your document, and the file goes to your computer automatically.
- You need printer software installed on your computer first; this usually comes on a disc with the printer or can be downloaded from the manufacturer's website.
- USB scanning works immediately after you plug in the cable, while WiFi scanning requires both devices to be connected to the same home network.
- Scanned files typically save as PDF or JPG in a default folder, which you can change in the printer software settings.
Installing the printer software your computer needs
Before you can scan, your computer needs the printer's software installed. This software tells your computer how to communicate with the scanner. If your printer came with a disc, insert it into your computer and follow the on-screen instructions. If you don't have the disc, go to the printer manufacturer's website — HP, Canon, Epson, Brother, Xerox, and others all have download pages — search for your exact printer model, and download the software package labeled "drivers" or "full software suite."
On Windows, the installer will walk you through connecting the printer by USB or WiFi. On Mac, the process is similar but you may need to add the printer through System Preferences > Printers & Scanners after installing the software. Once installed, restart your computer. The software is now ready to receive scanned documents.
Connecting your printer by USB cable
USB is the most straightforward connection. Plug the USB cable from your printer into an available USB port on your computer. Windows will usually recognize the printer automatically and install basic drivers if you haven't already installed the full software. On Mac, go to System Preferences > Printers & Scanners, click the plus button, and select your printer from the list.
Once connected, place your document in the printer's document feeder (the slot at the top) or on the glass scanning bed, depending on your printer model. Press the scan button on the printer itself — it's usually labeled with a picture of a document or the word "Scan." The document will scan and the file will appear on your computer, typically in a folder called "Scans" or in your Documents folder.
Connecting your printer over WiFi
WiFi scanning lets you scan without a cable, but both your printer and computer must be on the same home network. First, connect your printer to WiFi using the printer's touchscreen menu or buttons. Look for a WiFi or network settings option, select your home network name, and enter your WiFi password. The printer will display a confirmation message once connected.
Next, install the printer software on your computer as described above. During installation, when prompted to select a connection type, choose WiFi or Network instead of USB. The installer will search for your printer on the network and add it automatically. If it doesn't find it, you may need to enter your printer's IP address manually — this number appears on the printer's network settings screen or on a test page you can print from the printer's menu.
Once set up, you don't need the USB cable. Place your document in the scanner, press the scan button on the printer, and the file will appear on your computer just as it would with a USB connection.
Where your scanned files go and how to change the location
By default, scanned documents save to a specific folder on your computer. On Windows, this is usually your Documents folder or a subfolder called "Scans." On Mac, it's typically your Documents folder. You can change this location through the printer software settings.
Open the printer software on your computer — on Windows, search for your printer name in the Start menu; on Mac, look in Applications > Utilities or Applications > Printers. Find the settings or preferences section, look for "scan destination" or "save location," and choose a different folder if you prefer. Some people create a dedicated folder for scans so they're easy to find later. Once you change the setting, all future scans will go to the new location.
Choosing between PDF and image file formats
When you scan, the printer software saves the file in a format — usually either PDF or JPG. PDF is better for documents with text because it preserves the layout and is easier to share or print again later. JPG is better for photos or images because the file size is smaller. Most printer software defaults to PDF, which works well for most documents.
To change the format, open your printer software settings and look for "file type," "format," or "save as." Select PDF or JPG depending on what you're scanning. If you're scanning a multi-page document, PDF is usually the better choice because it keeps all pages in one file. If you're scanning a single photo or image, JPG works fine.
Troubleshooting when the scan doesn't appear on your computer
If you press the scan button and nothing happens, first check that the printer software is installed and your computer recognizes the printer. On Windows, go to Settings > Devices > Printers & Scanners and look for your printer in the list. On Mac, go to System Preferences > Printers & Scanners. If your printer isn't listed, reinstall the software.
If the printer is listed but scans still don't appear, check the scan destination folder. Open the folder where scans are supposed to save — usually Documents or a Scans subfolder — and look for recent files. If files are there but you didn't see them, the software is working; you just need to look in the right place. If no files appear, restart both your printer and computer, then try scanning again. If you're using WiFi, make sure both devices are still connected to the same network by checking the printer's network settings menu.
Frequently Asked Questions
Can I scan directly to my email or cloud storage like Google Drive?
Some newer printers have this feature built in, but most don't. Instead, scan to your computer first, then attach the file to an email or upload it to Google Drive, Dropbox, or OneDrive manually. A few high-end printers let you set up email scanning through their software, but you'll need to check your printer's manual or manufacturer website to see if yours supports it.
What if my printer has a touchscreen but no physical scan button?
Use the touchscreen menu to find the scan option — it's usually labeled "Scan to Computer" or "Network Scan." Select it, and the printer will send the scanned document to your computer just as if you'd pressed a physical button. The file will appear in your default scan folder.
Why is my scanned document blurry or hard to read?
Check that the glass bed or document feeder is clean — dust and smudges reduce scan quality. Also make sure the original document is placed straight and flat against the glass. In your printer software settings, look for a quality or resolution option and set it to "high" or "300 DPI" or higher for text documents. Higher resolution makes files larger but much clearer.
Do I need to install software if my printer is already on my WiFi?
Yes. Just because your printer is connected to your WiFi doesn't mean your computer knows how to scan from it. You still need the printer software installed on your computer so the two devices can communicate. Without it, your computer won't recognize the scanner.
Can I scan multiple pages into one file?
Yes, if your printer has an automatic document feeder — the slot at the top where you stack multiple pages. Load all pages face-up in the feeder, press scan, and the printer will feed them through one at a time and combine them into a single PDF file. If your printer only has a glass bed, you'll need to scan each page separately and then combine them using free software like PDFtk or online tools.
