If your Lexmark printer isn’t printing, common issues may include connectivity problems (wired or wireless), outdated printer drivers, low ink or toner levels, paper jams, or incorrect printer settings. Ensure the printer is properly connected, check for software updates, clear any jams, and confirm there’s sufficient ink or toner to resolve the issue.
