Use a combination of “enable” and “enables” after saying two different kinds of the same thing.
What is the purpose and purpose of the XYZ inkjet printer? Should
this be enable as you’re referring to two different things, or is it enables because you are referring to two singular things?
How do I spell out “The portable inkjet and wireless color photo printer “, should the printer be plural or singular there? Sitting I’m guessing if it stays singular then it would be enable and not
enable.
2 things in one unit is two things, and the two things “enable”. Is it more common in American speech for people to follow the singular word, so far away from printers, with “enable”?
I would say that “printers.. each enable” both is right and sounds right.
From the user’s point of view, not the mechanic’s, is your unit essentially all one device, such as something that prints everything out the same port? This will tell you if it is a singular
or plural.
