Running Windows 8.1 and Office 2013. Have a Canon 4370dw Laser Printer connected to my desktop via USB. Have a Brother MFC-J475dw inkjet connected wirelessly to the network. Default printer is the Canon. Here's the problem:

Word - In print dialogue, I can choose to print from either the Brother or Canon with no issues
Notepad - Same. Can choose whichever printer I like
Excel - Can see the Brother printer and it's online. When I click the Brother printer to select it, the Canon stays selected. It simply won't switch to the Brother although the printer dialogue box appears exactly the same in Excel as it does in Word.

Have run printer troubleshooting. Have re-installed Brother drivers and software. Have searched the web for a solution or someone that has had same problem. No luck. Any suggestions on what I can try next or what the problem might be? I'm surprised since I'm assuming that Word and Excel use the same printing module / dll.
