Q: My printer fan runs all the time even when I'm not printing for hours at a time. I live in California and the power waste is not real cool here. Help.

A: You can use the program /usr/etc/nppower to turn on and off the printer's fan. The printer will automatically turn on when one of your users begins to print something. To turn off the power at any time type /usr/etc/nppower off. If you want to turn off the power at 6 p.m. every day, put this line in the file /usr/lib.crontab on the computer that has the printer: 0 18 * * * root /usr/etc/nppower off
