HP2 is a graphics file format used by printing devices. HP2 files contain scripts written in HP-GL, a printer control language for printers and plotters manufactured by Hewlett-Packard.

HP2 files are typically used by professional print shops. Modern printers and plotters no longer support this format. HPGL langage is less popular than more universal PCL standard. Some image viewers offer a function to convert HP2 file to other image formats.
