From what I read on your issue how about plugging the laptop into a basic wifi router (any one will do even 2nd hand on eBay cost peanuts) rename this router ssd "copier" set DHCP on the copier allow it to obtain an IP address.
Now all you have to do is set this IP into the print drivers & tell the users each time they want to print or scan is connect to your newly created "copier" network.
You could get this new router to connect to their existing wifi network & act as a range extender etc. I do this all the time with churches or charities with no IT support.
Or you could go down the powerline route these work well with very little IT knowledge they're pretty much self installing.
