As rarely as this would be used (several times a MONTH), there would be no point in even using the standby mode. The good old fashioned on-off switch is right there. As to the cost of the printer to operate in standby mode, even if we are talking about something that consumes some 5 watts in standby, at our proposed increased power prices of $0.12 per kWh, $100 buys you: $100 / $0.12 * 1000 watt-hours / 5 watts = 166,666.7 hours of operation, or about 19 years. But, with a complete implementation of an on-off switch method of energy conservation, most likely the payback time is far longer. But, putting in a simple very old computer with very old printer and an ethernet cable sticking out of it for anyone to plug their laptop into is far, far less expensive than the current method of running five miles down the street to Lazerquick and printing it there. *One* printout would basically pay for the time required to set this up - especially if we are talking about a Mac network system vs. certain other hardware that is quite a bit more cumbersome to install in a network fashion. -- -Glennl Please note this e-mail address is a pit of spam, and most e-mail sent to this address are simply lost in the vast mess.

In my case, although it was rarely used, the printer was in a room away from the computers that were using it. The computers were scattered over two floors, so someone would have to either get up and go turn it on interrupting their work flow, or yell out or call on the phone for someone closer to turn it on, interrupting several people's work flow. I once had a guy working for me that I forbade to take "the printer is broken or out of paper or jammed" calls. I told him to pass them on to the person on duty (as it were) because if he got up to fix a printer, even one 10 feet from his desk, it would be an hour before he got back to working. Although this is a home printer now, my son is like that. He would get up to turn on the printer and never go back to his homework. He'd get back to the computer, but why not check his email, look up his friends on facebook, play a game, etc. People who work from home or in small offices are more likely to be that way. Too many distractions and not enough supervision. There also is the theory that what kills electronics is onrush current, so it is better to turn it on and leave it on than to keep turning it on and off. Laser printers are especially bad that way. On standby they leave their fusers off until they are needed, but always turn them on when you power them up. If you turn on the printer in anticipation of printing, but don't print, you've wasted a lot more electricity than if you left it in standby. Geoff. -- Geoffrey S.
