Jaguar (Mac OS X 10.2) includes CUPS (Common UNIX Printing System). This means that you no longer have to separately configure the Unix command-line printing (commands lpr, lpq etc.). You get a list of the available printers with the command

lpstat -p

After this you can use, e.g., the command

lpr -Pprinter_name file

CUPS can be controlled with a web browser at the local address http://127.0.0.1:631 (this can only be used from the local computer). Also manual pages are available through this address.
