Postscript (not the P in PDF, even though I think it should have been) is how Portable Document Format is made.
PostScript’s original purpose was for formatting documents to print with laser printers, but to also interpret font hinting and display features for lower resolution printing. But it required printers to process them before rasterization.
It was so good at this that it made sense to also use it for the much lower resolution of computer screens once computers were powerful enough to do the rasterization themselves. Hence the PDF replacing most .PS (PostScript) files, unless you were a graphic design student in the late 90s.
