Adding Printer2 to a homegroup controls sharing visibility across the home network but has no effect on which printer is designated as the default.

Windows 10 includes a setting called 'Let Windows manage my default printer' that automatically promotes the most recently used printer to default based on location context. Disabling this setting in Settings > Devices > Printers and scanners prevents Windows from overriding the manually configured default. Once disabled, Printer1 will remain the default printer regardless of which printer was last used.

Printer priority (range 1-99, where 99 is highest) determines job scheduling precedence when multiple logical printers point to the same physical device, not which printer is set as the system default.

Setting Printer2's priority to 1 assigns it the lowest scheduling priority, which does not affect default printer selection and would not prevent Windows from changing the default to Printer2.
