Hi Kemp.
Windows 10 has significant differences from the operating systems that were available when the PRO-100 was initially released (Windows XP). Because of that, the updated drivers on the Canon U.S.A. website are necessary.
Downloading the drivers to your computer does not require the PRO-100 to be present; the printer only needs to be present for the installation process. To give an analogy, downloading is like buying new windshield wipers at the store (you don't need the car present to make the purchase), while installing is like putting the new wipers on the car. For quick reference, the driver download page is: https://www.usa.canon.com/internet/portal/us/home/support/details/professional-large-format-printers...
If prompted to "Save or Run", select Save. As of this writing, the necessary driver is the "PRO-100 series Printer Driver Ver. 1.06", and the default filename is "p86l-win-pro_100-1_06-ea32_2.exe". You may wish to check your Downloads folder to see if this file is present; if so, you may run it once you're back with the PRO-100.
If connecting by USB, your Yoga may need to be connected to external power. If it's running on battery power, it may power down the printer's USB port occasionally from lack of use, or experience too low of a signal strength for the printer to detect or respond.
