1. Verify that the printer is turned on (green/orange status light) and the USB cable is connected.

  2. Verify the printer tray has paper and no jams exist in the feeder.

  3. Navigate to Control Panel > Devices and Printers:A. Verify the printer icon is not grayed out (this would indicate the printer is disconnected).
    ← This printer is offline
    B. Verify the printer is set as default. A green check mark will appear over the default printer.

    C. Navigate to Printer Properties > Ports and confirm “USB001. Virtual printer port for USB” port is selected. If another port is selected, change to USB001.
    D. Verify the correct driver is appearing under Printer Properties > Advanced > Driver. The driver name should match the printer model (for HP models, Universal Drivers should also suffice)

  4. Navigate to Device Manager > Printers. Verify that the printer appears listed.

  5. If the printer is appearing disconnected in Device Manager or Devices and Printers, replace the USB cable and attempt connecting to different USB ports. Sometimes printers do not function with USB 3.0 ports. If the printer is appearing connected but still does not connect, it is likely a software related issue.

  6. Navigate to C:\Windows\System32\spool\PRINTERS. Delete all files located in the folder to clear the existing print queue.

  7.  Open Services and restart the “Print Spooler” service. Verify that the service starts and runs. The service status can be queried by running command sc query spooler.

  8. Attempt printing a test page. This test can be completed multiple ways:
    A. Open Command Prompt and run command DIR >> UBS001. Check if a page is printed.
    B. Right click the printer and navigate to Printer Properties > General > Print Test Page. Check if a page is printed.

  9. If printer is still not printing, remove the device from Devices and Printers and reinstall the driver.
