What is the difference between .hpgl and .pfm?

Description: The HPGL file format, standing for HP Graphics Language Plotter File, is a specialized file type developed by Hewlett-Packard. It is primarily used for controlling plotter devices, which are printers that draw images with lines instead of dots, making them ideal for engineering and architectural drawings. HPGL files contain a series of two-letter instruction codes followed by parameters that direct the plotter's drawing operations, such as moving to a point, drawing a line, or selecting a pen.; A Printer Font Metrics (PFM) file is a type of file associated with Adobe Type 1 fonts used in Microsoft Windows. It contains metric information about a font, such as character widths, heights, and kerning pairs, which are essential for correctly displaying and printing text. The PFM file works in conjunction with a PFB (Printer Font Binary) file, which contains the actual font outline data.
