Drivers and Their Importance Device drivers are software intermediaries that translate operating system print commands into device-specific instructions. For thermal printers like the XPK-200L, drivers ensure correct page formatting, proper control of cutter and buzzer features (if present), accurate character encoding for receipt text, and management of print density and speed. Without the correct driver, Windows 10 may only provide a generic USB printing interface that can result in misaligned output, unsupported features, or failure to print at all.
