Questions & Answers
HPGL files: Frequently Asked Questions
What are HPGL files?
HPGL (filename extension .hpgl or .hpg) is a vector graphics file format developed by Hewlett-Packard for controlling pen plotters. Introduced in the late 1970s, it became an industry standard for technical drawing applications, computer-aided design (CAD), and large-format printing.
The format consists of ASCII text commands that instruct plotters on movement (e.g., PU for Pen Up, PD for Pen Down), line drawing, and text placement. HPGL files are lightweight and device-independent, making them suitable for archival storage of vector-based designs.
