There are a few signal guides on this site and on the associated ProProfs test modules. If you want a paper copy but don't have a color printer you can stop by a FedEx Kinko's and print it there. To do that you can either save the file to a flash drive and bring it to FedEx in person, or, email the file to FedEx https://www.fedex.com/en-us/printing/printandgo.html and print it at a FedEx Kinko's using the Print & Go service.
