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 :-)

>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.
