>The same is true of copiers - we put a copier into the office and blew out 2 offices' power when it went on. It was even worse than the Laser Jet II we had (OK, this was several years ago :-)
Funny thing about that - they work in a very similar fashion :-)
Really, any heavy-draw office equipment needs to be kept off of a UPS. Space heaters are another pet peeve in my office. As a general rule of thumb in my office, PCs, monitors, modems, hubs and the like go on the UPS - the things that need to stay running to give you a chance to undergo an orderly shutdown in the event of a power failure. Anything else goes on a line conditioner.

>>A typical laser printer can draw upwards of a KW (1000W) for brief periods of time - it's never advisable to connect a laser printer to a UPS, espcially with other devices. If you're going to connect a laser to any kind of power protector beyond a simple surge suppressor, consider using a CVT (Constant Voltage Transformer), aka Line Conditioner, to protect against brownouts - if even a small laser is up and active on a battery, even a 2KVA unit, you're likely to damage the battery.
