Hi Jodie,
Its possible that this is happening because windows is trying to select a default printer for you.
On your computer, go to the Printers & Scanners page and select the printer that you would like to be as default. Then from within the program, you can go to File > Preferences > Overall Settings.. and select the default printer there.
Then test it out! If it still isn’t working correctly after that, I would suggest to contact our support department by calling 1.866.697.2020.
Regards,
Kris
