Printer is on but not printing: what to really do

Turn on the printer, start printing a document, everything seems fine… but nothing happens. No noise, no movement, and the paper stays in the tray. This situation often occurs, both in the office and at home, with any type of printer: inkjet or laser, connected via USB cable or Wi-Fi.

In this guide, we explain step by step what to check and how to solve the problem, avoiding drastic solutions like formatting the PC or buying a new printer.

1. Check connections: cable, USB port, and Wi-Fi

The first check should be on the connection between PC and printer:

• USB cable: disconnect and reconnect both ends. Also try another USB port on the computer.
• Network printer: make sure it is properly connected to the Wi-Fi network. Sometimes restarting the router and printer is enough.
• PC settings: check that the printer is active and visible in “Printers & scanners.”

A loose cable, an unstable wireless connection, or a malfunctioning USB port can block data from being sent to the printer.

2. Is it the default printer?

Often the problem is simply this: the operating system is sending the file to a “virtual” or offline printer. On Windows:

• Go to Settings → Devices → Printers & scanners
• Select your printer and click “Set as default”

If you use PDF Creator or Cloud printers, they may be mistakenly set as default.

3. Check the print queue

Many problems come from stuck print jobs:

• Open the printer queue (right-click on the printer → See what’s printing)
• Clear all pending jobs
• Restart the “Print Spooler” service if you are on Windows (from Services)

In many cases, simply restarting the printer and PC after clearing the queue is enough.

4. Check the printer status

Look for error messages on the display, blinking lights, or software notifications. Some signals not to ignore:

• Red or blinking ink light
• Screen indications: “out of paper,” “paper error,” “incorrect paper loading,” etc.
• Driver software messages: “Printer offline,” “Cartridge not recognized”

5. Check the ink or toner

If the cartridges are empty or unrecognized, the printer may jam:

• Open the printer software panel on your computer
• Check the cartridge levels
• If you have used compatible or refilled cartridges, consider replacing them with original ones

Some printers completely block printing if even one cartridge is not recognized.

6. Update or reinstall the drivers

Outdated or corrupted drivers can be the invisible cause of the problem:

• Download the latest drivers from the manufacturer’s official website
• Completely uninstall the printer and reinstall it from scratch
• Avoid using generic automatic drivers offered by Windows

7. Print a test page

To understand if the problem is from the PC or the printer, perform a standalone test:

• From the PC: right-click on the printer → Properties → Print test page
• From the printer: press and hold the “Stop” or “Info” button for 5-10 seconds (depends on the model)

If the test page prints correctly, the problem is software. If it does not print, it is hardware.

8. The printer is connected to the network but does not print

Many modern printers work only via Wi-Fi connection:

• Check that it is connected to the correct network
• Open the printer configuration panel and check the IP address
• Try printing from another device on the same network

A common error is that the router assigns a different dynamic IP each time: set a fixed IP for the printer.

9. Interference from firewall or antivirus

Security software sometimes blocks communication between computer and printer:

• Temporarily disable the firewall or antivirus
• Add the printer or printing software to the exceptions list
• Check the security settings of the home network

If the problem disappears after disabling, the antivirus is the cause.

10. When it’s time to contact support

Have you checked everything, but the printer still won’t print? It’s time to:

• Check if it is still under warranty
• Contact the official support of the manufacturer
• Have a technician diagnose any hardware failure

Avoid DIY internal interventions, especially if the printer is still covered by warranty.

Bonus: printing from smartphone and tablet

Many modern printers support printing from mobile devices, but problems can still occur:

• Check that the manufacturer’s app (e.g., HP Smart, Epson iPrint) is updated
• Make sure the mobile device is on the same Wi-Fi network as the printer
• If you use AirPrint or Google Cloud Print, check compatibility

To easily print from mobile devices, it’s best to use official apps or printers with connection QR codes.

Conclusion

Your printer doesn’t print? In most cases the solution is simpler than you think: a wrong connection, an outdated driver, a stuck print queue. By calmly following these 10 points you can solve almost every problem without wasting time or money.
