Final answer:
Printer Command Language (PCL) is a page description language used to control the printing process on printers. Developed by Hewlett-Packard, it has become a standard for formatting text and graphics in print jobs. Users generally don't deal with PCL directly; it's used by printer drivers to communicate with printers.
Step-by-step explanation:
The PCL language of a printer stands for Printer Command Language. PCL is a page description language (PDL) developed by Hewlett-Packard as a printer protocol and has become a de facto industry standard. Primarily used for controlling the printing process, it provides instructions to the printer about how to format text, handle fonts, and arrange graphics on the page.
PCL has gone through various versions, with PCL 6, also known as PCL XL, being the most recent version. Each version has added more sophistication and control over the previous ones, enabling better printing of complex documents and graphics with higher quality and at greater speeds.
Users typically do not interact with PCL directly. It's used behind the scenes when a document is sent to print. The printer driver on a computer translates the document into PCL commands so that the printer understands how to print it accurately.
