Symptoms

  • Print jobs go to the wrong printer unexpectedly
  • Default printer setting shows a different printer than usual
  • Happens after connecting to a new network or printer
  • Manually resetting the default doesn't stick

Likely causes

  • CommonWindows 'Let Windows manage my default printer' setting enabledThis feature automatically changes your default to whichever printer you used most recently.
  • CommonA new printer was recently added or auto-detectedAdding a new printer, including a PDF or fax 'virtual' printer, can shift the default.
  • PossibleConnecting to different networks with different available printers (laptops)Some setups automatically pick a 'closest' or 'last used' printer per network.

What to do

  1. On Windows, go to Settings > Bluetooth & devices > Printers & scanners and turn off 'Let Windows manage my default printer.'
  2. Manually select your preferred printer and click 'Set as default.'
  3. Check for and remove any unnecessary virtual printers (like unused PDF printers) that may be getting selected accidentally.
  4. On Mac, go to System Settings > Printers & Scanners, and set the 'Default printer' dropdown to 'Last Printer Used' or a specific fixed printer based on your preference.
  5. If using a laptop across multiple networks, expect the default to potentially change per location, and simply reselect the correct printer at print time if needed.
  6. Restart the computer after changing the default printer setting to confirm it holds.
