Compatibility with Windows 10 adds another layer of consideration. While Windows 10 is known for its backward compatibility, the XP-80C’s drivers were originally designed for older systems like Windows 7, XP, and even embedded POS systems. The user must often choose between a 32-bit and 64-bit version of the driver, depending on their Windows 10 installation. Furthermore, modern Windows 10 security features, such as driver signature enforcement and SmartScreen filters, may block or warn against installing older, unsigned drivers. The user must then navigate to advanced startup options or temporarily disable these protections—a daunting task for the non-technical user. Interestingly, many users have found success not with an official Xprinter driver, but with a “Generic ESC/POS Printer Driver” included with Windows 10, or with drivers from other brands like Epson, highlighting the standardization of underlying command languages.
