Two of the most recognized and widely used printer languages in the industry are PCL (Printer Command Language) and PostScript.

Each one comes with unique advantages and is suited for different types of environments and workloads.

PCL, developed by Hewlett-Packard, is a standard language found in many office printers. It’s built for speed and efficiency—great for high-volume text documents and general-purpose printing. Because it communicates quickly and uses fewer system resources, it’s favored in many Windows environments.

However, it’s device-dependent, meaning the output may vary slightly between printer models. For most office tasks like printing emails, invoices, or reports, PCL does the job efficiently.

PostScript, on the other hand, was created by Adobe and is known for its precision in handling complex images, graphics, and layouts. It’s often used in publishing, graphic design, and professional printing environments where consistent, high-quality output is critical.

Unlike PCL, PostScript is device-independent, so the output looks the same across different printers. It handles fonts, vector graphics, and layers better than PCL, making it essential for Adobe-based workflows, PDF printing, and macOS environments.

For technicians preparing for the A+ exam, understanding the difference between these two languages is vital. Installing the wrong driver—PCL when PostScript is needed, or vice versa—can result in formatting errors, misaligned content, or failed print jobs.

Technicians must know how to select the right printer driver, troubleshoot issues related to incorrect language settings, and identify which language best suits the user’s workflow.
