Hello, I am Alina, Working as SEO Executive since last 2 years.
If your HP printer not printing, it's possible that the papers have been stuck within the printer. Since numerous jobs must be completed, the printer does so without pausing. In that process, the printer must have got trapped within the printer. You must first open the tray before removing the paper. When this occurs, it's a difficult scenario. This is because you will need to gently remove the paper that has been trapped within the printer.
