If your Lexmark printer is not working after a Windows update, the issue may be caused by driver incompatibility or system conflicts. Restart your computer and printer first. Then uninstall and reinstall the latest compatible driver from the official Lexmark website. You can also check for additional Windows updates or roll back the recent update to restore proper printing functionality. https://printerithelp.com/lexmark-printer/lexmark-printer-issue-after-windows-update
