5. Run the Printer Troubleshooter: Windows has a built-in troubleshooter that can detect and fix problems related to printing. Go to Settings > Update & Security > Troubleshoot > Additional troubleshooters > Printer, and run the troubleshooter - learn more.

6. Print a Test Page: Most printers have an option to print a test page, which can help determine if the printer hardware is working correctly. Access this option from the printer settings on your computer or directly from the printer’s menu - learn more.

7. Inspect Hardware: Check for any blockages or obstructions inside the printer. Paper jams or issues with the ink cartridges could also lead to printing blank pages. If necessary, clean the print heads or replace any faulty cartridges - learn more.
