Answer:
You said "paperless log question". ??? Just in case you meant that:
Paperless logging is the same as paper book logging. Same rules, etc -- it's just the computer recording it for you instead of writing it yourself in an actual paper "book". To review or display your logs, you have to use the truck's QualComm screen, or have a print-out sent to a fax machine from the company's office.
