Printer Not Printing

Updated Yesterday · 3 min read

If your printer is not printing, follow the steps below to identify and resolve the issue.

1. Check if the Printer Is Powered On

First, make sure the printer is turned on.

  • Look for the power indicator light on the front of the printer.

  • The light should appear yellow-green, indicating that the printer is powered on and ready.

If there are no lights visible:

  • Check the power cable connection

  • Make sure the power outlet is working

  • Try turning the printer on again

2. Check the Printer Cable Connections

Make sure the printer cable is securely connected.

Inspect:

  • The connection between the printer and the booth/Mini PC

  • Any USB or printer cables for loose connections

If needed:

  • Disconnect and reconnect the cable securely

  • Ensure the cable is fully inserted into both ports

3. Check if the Mini PC Detects the Printer

On the booth Mini PC:

  1. Open Control Panel

  2. Select Devices and Printers or View Devices and Printers

  3. Locate your printer in the list

If the Printer Is Online

  • Right-click the printer

  • Select Printer Properties

  • Click Print Test Page

If the printer successfully prints a test page:

  • The printer is working correctly

  • Double-check your booth software or Global Settings to ensure the correct printer is selected

  • Run a live test by taking a photo and printing it

If the Printer Is Offline or Grayed Out

This means the Mini PC is not detecting the printer properly. Continue with the steps below.

Additional Troubleshooting Steps

4. Bypass the USB Hub

If the printer is connected through a USB hub:

  • Disconnect it from the hub

  • Connect the printer directly to the Mini PC instead

You can also try different USB ports on the Mini PC.

5. Try a Different USB Cable

A faulty USB cable can prevent communication between the printer and the Mini PC.

  • Replace the current USB cable with another one if available

  • Recheck if the printer appears online afterward

6. Restart the Printer and Mini PC

  1. Disconnect the printer from the Mini PC

  2. Restart the Mini PC

  3. Turn the printer off and back on

  4. Reconnect the printer once the Mini PC has fully restarted

This refreshes the printer connection and can resolve detection issues.

7. Check the Power Cable and Outlet

Sometimes the issue may be power-related.

Try:

  • Using a different power outlet

  • Testing with another compatible power cable if available

8. Restart the Print Spooler Service

The Print Spooler manages print jobs in Windows. Restarting it can fix printing issues.

How to Restart the Print Spooler

  1. Press Windows + R

  2. Type services.msc and press Enter

  3. Locate Print Spooler

  4. Right-click it and select Restart

Once restarted, try printing again.

9. Check for Windows Updates

Missing or outdated Windows updates can sometimes affect printer communication.

How to Check for Windows Updates

  1. Open Settings

  2. Go to Windows Update

  3. Click Check for Updates

  4. Install any available updates

  5. Restart the Mini PC if prompted

After the update, test the printer again.

Additional Suggestions

To make troubleshooting easier, you may also want to include these recommendations:

  • Label the correct printer in the software settings

  • Avoid using damaged or extended USB cables

  • Keep printer drivers updated

  • Make sure the printer has enough paper and media loaded

  • Check the printer screen for error messages or paper jams
