The line printers had been designed from the beginning as computer peripherals, because previously there was no need for such high printing speeds. They were called line printers because all 132 characters of a line were printed simultaneously, by impact.
The first computers were not multitasking, so they could not be used for anything else while printing. Because of this, a very high printing speed was necessary, which required the development of the line printers. Later, when printing no longer blocked the execution of other tasks, the very expensive line printers could be replaced in many cases by cheaper printers, like dot-matrix printers or daisy-wheel printers.
Many more recent operating systems, like Unix or MS-DOS, have kept the abbreviation LPT for printers, even if by that time the line printers were already obsolete and they were very seldom encountered.
All early experimental computers used teletype machines for interactive communication with the computer. In the later commercial computers, teletypes continued to be used for the operator console, while the batch jobs of the non-privileged computer users would have had only the line printer or the card puncher as output peripherals.
If there have ever been any teletypes with an output width greater than 80 columns, they must have been very seldom used. At the standard typewriter pitch of 10 cpi, 132 characters require paper with the width of 14 inches (including the perforated margins). That would have required a huge teletype. I do not believe that such a big teletype has existed.
