Copy the named files to LP subsystem spooling directories. Normally, the files are linked into a spool directory. The ownership and mode of the linked files remain unchanged. The ownership and mode of the copies are set to allow read access to owner lp and group bin only. If the files are linked rather than copied, any changes made to the named files after the request is made but before it is printed will be reflected in the printed output.
Standard input is always copied instead of linked.
If dest is a printer, the request will be printed only on that specific printer. If dest is a class, the request will be printed on the first available printer that is a member of the class. If that variable is unset or empty, the default queue is used, if one has been defined. By default, no mail is sent upon normal completion of the print request. Specify a printer-dependent option .
