You can either use Windows Settings, Control Panel or Command Prompt to set default printer on your computer.

Let me quickly show you the steps for all three methods.

Using Windows Settings

• Open Settings > Bluetooth & devices > Printers & scanners.
  
• Turn off this option that says “Let Windows manage my default printer”. Otherwise, it will only mess with the default printer settings🙄
  
• Then, choose the printer which you want to make default.
• Click the Set as default button. That’s all.
  

Using Control Panel

• Open Control Panel > View devices and printers.
  
• Depending upon the layout of your Control Panel, you may not see this View devices and printers option. In that case, use the search bar in the Control Panel to find it.
• Once you see the window with all the printer profiles installed on your computer, right-click your desired printer > choose the Set as default printer option.
  

Using Command Prompt

• First, disable this option from Windows Settings.
  
• Then, open Command Prompt as administrator.
  
• Copy-paste this command there and press the Enter key: wmic printer get name,default
• It will list all the printers installed on your system.
  
• One with the TRUE label is the current default printer.
• Copy-paste this command again and press the Enter key: rundll32 printui.dll,PrintUIEntry /y /n "printer name"
  
• Instead of “printer name”, type your printer’s name which you want to set default.
• You’re done.
