If you have more than one printer that you can print to, you may need to occasionally reset your default printer (the printer that you want your documents to automatically print to).

Step 1:  Click on Start
Step 2:  Click on Settings
Step 3:  Click on Printers
Step 4:  Right mouse click on the printer that you want set as your default printer.
Step 5:  Click on Set As Default.

You can check to see if it worked by right mouse clicking on the printer again.  There should be a check mark beside Set As Default.
