Windows

First time PowerShell programmer
Ok so I have an environment that uses IP printing
We have several different printers
I would like to use power shell to script the addition of printer.
I found a power shell script that will do that (see below) I have taken out items that are specific to my business.
What I’m trying to figure out is where (or how) do I set the execution policy to run.
The policy is set to restricted, so I know that I can temporally set it to prompt so the printers can be installed.
I’m pretty sure that it can’t be done within powershell.
Here’s the script, I just need to figure out how I get it to run.
