What type of stationary is a business letter typed on?

A business letter can be written on plain paper or on letterhead, paper pre-printed with a company (agency or organization) name, address, logo, etc.

A business letter on plain paper should have the sender's address placed at the top right of the page above the date, centered at the top middle of the page, or for a full block style, at the top left above the date.

If you are a small business or organization using plain paper, include the name of the company or organization above the sender's address.
