By default, all printing is duplex, unless the user specifies otherwise. Printing a file To print a file, use the lpr command, followed by the name of the file you want to print. You can change your default printer using the -P option with the lpr command. Specifying non-stapled output By default, all output is stapled before being placed in the output racks. If you need unstapled output, use the -J option to the print command.
Unstapled output is held behind the racks.
You must ask the operator on duty for your unstapled ouyput. Hence, this option also provides greater privacy than default printing, which is placed in racks accessible to all users. Busing output to another location Output can be transported to several locations around the University. Without options, lpq shows the status of the currently defined default queue. Using the -P option, you can see the status of other queues.
