The Lexmark X1100 series (including the X1150, X1185, and others) is a legacy device. Windows 10 does not include "Plug and Play" drivers for it, and the original installation CDs will likely fail. To fix this, you must use the Windows Vista 64-bit or 32-bit driver, which shares the same underlying architecture as Windows 10. Step 1: Download the Correct Driver Package

Finding a reliable Lexmark X1100 driver for Windows 10 can be a challenge since this printer series was released long before Windows 10 existed. Because Lexmark no longer provides official updated installers for this specific legacy model, you have to use a workaround involving Vista-era drivers and Compatibility Mode.

The printer driver often installs successfully, but the scanning software (Lexmark All-In-One Center) may not. If this happens, try using the native Windows Fax and Scan app or Windows Scan from the Microsoft Store to see if the TWAIN driver is recognized.
