Rundll message with Pixma TS952C


My computer is an HP Envy with Windows 10 purchased 5 months ago.  I have a Pixma TS9521C purchased about 8 months ago .I had to reinstall it (the printer) after my 4-month old computer had to be reset to factory condition and Windows 10 reinstalled. 

I had no problem printing before with the old computer or the new computer with the Windows10. During the time between the faulty Windows and the reinstalled Windows , I also installed the printer on an old laptop.  This was about 4 weeks or so ago..  The printer worked .

Two days ago neither the desktop or the laptop would print.There was a message on screen: Windows host Process Rundll 32. I clicked on it and it took me to the Canon web site.  

Does anyone know what this is and how I can fix it?
