Anyone who uses a computer as a part of his or her day-to-day life — business or personal — will eventually need to send a printed document to someone via email. The options are to attach the original document (not advised, usually), a scan of the document (acceptable, but tedious to the sender), or a pdf (portable document format) of the document. Whenever possible and practicle, the latter is the way to go.
PDF converters are listed as printer. There are many, many options for software to create a pdf. My personal choice is doPDF. It’s free, installs easily, and creates the pdf quickly and accurately from your Windows word processor of choice.
