A printer has just been installed on a client computer. When the technician prints to the printer, the characters are entirely garbled. What is the MOST LIKELY source of this issue?

The correct printer driver for the printer and operating system must be installed. For example, if you have an HP LaserJet Pro M15w and a Windows 11 machine, you must install a Windows 11 HP LaserJet Pro M15w driver. If this is not done, the printer will produce garbled characters. Although, the Windows operating system will provide some drivers for a printer, the manufacturer's driver often come with other software that provides additional features to use with the printer, and if the output is garbled, the manufacturer's printer drivers should be used rather than those provided by Windows.
