About PCL (Printer Command Language) Driver:

PCL Printer drivers are basically a set of small programs able to create an interface between your printer and the operating system on your personal computer. If your printer uses PCL protocol, it is imperative that you install these drivers in order to enjoy the full capabilities of your device.

Although PCL drivers offer a large number of features, they are not recommended for use in high quality printing as they don’t reproduce colors precisely.

Printer Command Language or PCL drivers are generally used for home or office printers because they offer very good compatibility (most printers use PCL), give less printer errors and are less demanding on your network connection.
