In WA state is it required that employers give you a physical copy of your W2 or is a digital copy acceptable?

Federal law requires all employers to send employees W-2 statements no matter how low earnings or wages are.  These W-2 statements can be sent in either paper or digital form and must be received by employees no later than January 31 of the following year. Employers must also file a copy of employee W-2s with the IRS.
