Format: printwindow [line] [num]
This command is most useful in non-GUI mode. Prints a window of text, num lines long, centered about line. The default value for num is specified by the system variable _LINES which defaults to 22. The default for line is the current line. See "System variables". The current line is indicated by a greater-than sign (>) in the left most print position. The current viewing position is unchanged.
