What steps will reproduce the problem
1. Login to a toon with the addon EquivalencePoints enabled
2. Enter the following slash command "/script print()
3. Error occurs in EquivalencePoints/libs/cba.lua

What is the expected output? What do you see instead?

A non-library addon should not override a global function...
The global function does not produce an error on empty arguments
The global function does not prepend the word "Output:" to the output text.

What version of the product are you using?

2.2.1

Do you have an error log of what happened?

Please provide any additional information below.

Is this library even needed since 3.0.2 now includes a print function?

The library (cba.lua doesn't indicate in comments why it needs to create a new global print function.
