The oddly named HP Graphics Language Plotter file or HPGL is a type of vector image file developed by Hewlett-Packard. These files contain printer instructions using the plotter language developed by HP – they are used to send info to plotter printers.
The info sent is used to draw images using lines instead of dots like a laser or inkjet printer might. These files don’t contain an image itself, merely instructions on how and where to draw the image, as well as a series of setup commands.
How can you open HPGL files?
Because of their highly specific nature, these files are always intended to be used by HP printers, however, they can be opened and edited by a variety of imaging programs across platforms and operating systems.
What programs work with HPGL files?
Imaging programs like the CorelDRAW Graphics Suite 2019, the Corel PaintShop Pro, ArtSoft Mach, and ACD Systems Canvas X can open these files. Additionally, dedicated viewers like ideaMK HPGL Viewer also accept HPGL files. On Mac and Linux, programs like Lemkesoft CADintosh and vhf interservice Cenon can open HPGL files.
