Step 1: Page Description Language When your PC is ready to print something, it needs to tell the printer how to print it, so it must include information about fonts, where to print text, how to print pictures, and so on. It does this by using the printer's page description language. The most common page description language is PCL, used by Hewlett-Packard printers. PostScript is a common page description language as well.
