Printer Control Language (PCL)
Printer Control Language (PCL) is a language (essentially, a set of command code s) that enables application s to control HP DeskJet, LaserJet, and other HP printers. Many personal computer users find themselves in need of PCL driver s (small programs that interface between the operating system and the printer) after purchasing a new HP or HP-compatible printer and attaching it to their existing PC and operating system. PCL drivers are available for downloading from the company's Web site.
