A Lexmark printer can go offline due to various reasons, including connection issues, printer driver problems, or printer hardware issues. If the printer is connected via USB, ensure that the cable is securely plugged in. Next, check if the printer driver is installed correctly and updated. If not, reinstall the printer driver from the Lexmark website. If the issue persists, try resetting the printer or contacting the manufacturer for support. https://printersofflines.com/lexmark-printer-offline/
