File>Print (shortcut: C+p) prints the current buffer.
File>Page Setup displays a dialog box for changing your operating system's print settings, such as margins, page size, print quality, and so on.
The print output can be customized in the Printing pane of the Utilities>Global Options dialog box; see the section called “The Printing Pane”. The following settings can be changed:
The font to use when printing.
If a header with the file name should be printed on each page.
If a footer with the page number and current date should be printed on each page.
If line numbers should be printed.
If the output should be color or black and white.
The tab size to use when printing - this will usually be less than the text area tab size, to conserve space in the printed output.
