A systems administrator connects a printer to a computer.

The correct answer is B. Drivers. A printer driver is required so the operating system can communicate with the printer. If the printer is connected and appears to be set up but still does not work, an incorrect, missing, or outdated driver is the most likely cause. Services, permissions, and extensions can affect some systems, but the most direct and common issue after printer setup is driver installation.

Exact Extract/Reference: The CompTIA Tech+ Study Guide states that, in addition to connecting the printer, “you need to install a special piece of software called a printer driver so the operating system knows how to talk to the printer.” The guide also explains that after hardware installation, the operating system either detects the device automatically or the user must install a driver manually.
