Hi layreader1810
I think that u need a new driver which compatible with your windows, you can download that driver from canon website or minehttp://driverproduct.blogspot.com/2015/08/Canon-Printer-PIXMA-MG7150-Driver-Download-Free.html
Before you install the driver, make sure that i downloaded the right driver for 32 or 64 bit windows 10
go to device and printets, right click and remove your canon printer list there
Next go to control panel, click uninstall all of your printer programs/drivers
Next step, restart your pc, install the printer driver, turn on and reconnect ur printer only when ask by setup, when it finished, install your scanner driver, restart one last time and then see how it print and scans
I dont have any idea if it still cant work properly but
Let me know if its not solve your problems
