This can happen if the Print Spooler related-file has become corrupted or gone missing. It could also happen if the concerned Windows Services are not functioning as they should. So to fix the issue, you can try the following suggestions:

1] Restart Print Spooler Service

Open the Services Manager. Locate the Print Spooler Service, right-click on it and select Properties. Change the Startup Type to Automatic and click on Start. Click on Apply and then on OK to save the settings. Now try and see if you can print.

2] Update the Printer drivers

To update drivers, press Win+R to open the Run window and type the command appwiz.cpl. Press Enter to open the Programs and features window. Locate the previously installed Printer drivers. Right-click and select Uninstall for them. Restart the system to complete the uninstall process. Connect to the Internet and then plug in the Printer to your computer now. The system will install the drivers automatically. If the system doesn’t install the printer drivers automatically, use the Add a printer wizard and the drivers can be downloaded from the manufacturer’s website.

It does the work by changing information in the registry as follows:

It removes non-Microsoft print monitors from {PrintRootKey}\Monitors, and moves them to {PrintRootKey}\Disabled Monitors.It scans all printer drivers in the printer’s key, and updates all print drivers that are using one of the disabled monitors and disabled them.It removes non-Microsoft print processors {PrintRootKey}\Environments{Architecture}\Print Processors, and moves them to {PrintRootKey}\Environments{Architecture}\Disable d Print Processors.It scans all printers in the printer’s key, updates all print drivers that are using one of the disabled print processors, and moves them to “WinPrint.” The old print processor configuration is stored on a registry value named “Disabled Print Processor.”
