One of the causes of the Lexmark Printer Offline issue is that the printer's settings are set to offline, which causes the printer to stop printing. As a result, you must change the online setting to an offline one. You should double-check whether the USB connection is working properly. The printer may become unavailable due to defective wiring. Only if you keep your drivers up to date on a regular basis will the printer work correctly. As a result, you must regularly update your driver. If the printer exhibits an offline error, look for hardware problems.
