What is an HP_ file

HP_ files mostly belong to HPGL Viewer. HP_. files are used to store drawing instructions in HPGL, the Hewlett-Packard Graphics Language. They are primarily a set of text-based commands that drive plotter hardware.
These files have two main applications:

Plotter Drawing: They contain commands such as 'PU' (pen up) and 'PD' (pen down) to control pen movements and create precise vector graphics.
Text Data: Some files carry Armenian text designed for use with HPGL-based viewers, blending plotter instructions with language-specific content.

FilExt.com note: The files are plain text and can be viewed with an HPGL viewer or even a text editor to inspect the command sequence. Using dedicated software ensures proper rendering and conversion if needed.
