Hi, DerrickL. I am using this forum to thank you for your suggestion to use the USB cable to install the Plug & Play drivers for my PIXMA TS6420a multifunction printer. I thought I had tried everything except that I no longer had the proper USB cable to execute this procedure. So, using an OLD USB cable (newer cables did not fit the In/Out -put port of the printer) with both a USB A/B on one end and a USB B end on the other end of the cable, the drivers installed and the printer worked on my Surface Pro 12" Snapdragon ARM64 CPU based hybrid laptop. Thank you!
