Hi John. Welcome to justanswer.
You need to update the drivers of your printer which are compatible with Windows 10. If you want me to install them for you then there is an option of Secure Remote Assistance. Else I will give you the link and you will need to install them by yourself.
CLICK HERE and install the Full Feature Software and Driver
If you get any difficulty then do let me know.
When is this error coming up? Are you able to download the file?
When you click on Download, choose DOWNLOAD ONLY (the second option). Reload that page and choose it.
You have to click on the circular dot in front of Download only
Then click Next
Are you able to download now?
Do you want me to install that for you. If I cannot solve your issue, you will get a refund.
