@Melonlity -- the limited graphics capabilities of dot matrix printers is precisely what made them obsolete when graphical user interfaces such as Windows and Mac OS became prominent. Setting fonts was an afterthought in the earlier days of computers, but it's a common practice to set preferred fonts in word processors and even download more to get the "perfect" one.
A dot matrix printer simply lacks the flexibility to handle custom fonts. Dot matrix printers and, indeed, anything that was primarily used with DOS was kind of like a typewriter -- you got one font style (sometimes more on higher end hardware) and you were stuck with it.
Still, there were some good things about dot matrix printers. Sure, there were alternatives built for DOS usage such as thermal printers, but a good dot matrix printer was sturdy. There are still some in use today that were new three decades ago and that is an eternity when it comes to hardware.
