A printer can be connected to a computer and powered on but still fail to print. Sometimes the problem is not the printer hardware or Wi-Fi connection. The computer may be using an incompatible driver, an incorrect printer entry, or outdated software.

Understanding how printer drivers work can help you diagnose printing problems without immediately reinstalling everything.
