<P>The <TT>lpr</TT> command is the standard Linux interface for printing files. From the command line, you can use <TT>lpr</TT> to print to many different types of printers and to request many different options. Later, you can check the status of your print jobs with the <TT>lpq</TT> command. If you change your mind and want to cancel a print job, you can do so with the <TT>lprm</TT> command. No matter what, you should read the latest edition of the Printing HOWTO for more information.</P>
