Prints an expression to the command line, or writes an expression to an open file

(princ [expr [file-desc]])

This function is the same as prin1, except control characters in expr are printed without expansion. In general, prin1 is designed to print expressions in a way that is compatible with load, while princ prints them in a way that is readable by functions such as read-line.



A string or AutoLISP expression. Only the specified expr is printed; no newline or space is included.


A file descriptor for a file opened for writing.

Return Values

The value of the evaluated expr. If called with no arguments, princ returns a null symbol.
