The original TeX fonts are rendered as bitmaps from an outline format that isn't very compatible with PDF (based on pen strokes rather than outlines). Some older toolchains embed these fonts as bitmaps. It doesn't look particularly good in a PDF.
There now are TrueType versions of these fonts, that are default in modern TeX distributions, but not everybody uses them. (Especially older papers.). There are some scripts out there to do substitution in ps files, but not PDF.
