Final answer:
The typewriter with wider spacing would have proportional spacing, where each character takes up a different amount of space based on its width.
Step-by-step explanation:
If William types his name on two typewriters and on one his name appears wider, that typewriter would have proportional spacing. In typewriters with proportional spacing, each character takes up a different amount of space based on its width. This allows for a more natural appearance of text and is commonly used in modern word processors.
