I've tried everything, but my printer still won't print fully. Could it be a hardware problem?

If you've exhausted all software, driver, and consumable-related troubleshooting steps, a hardware malfunction is a strong possibility. For inkjet printers, a faulty print head assembly that cannot be restored by cleaning cycles might be the cause. For laser printers, issues with the fuser unit (which bonds toner to paper) or other internal components could result in incomplete or poorly fused prints. In such cases, professional repair or replacement of the printer might be necessary.
