Inkjets normally work on less than 100 watts. Laser printers pull from 400 to 750 watts of power. I've found that laser printers impossible to use when running an ac inverter in my vehicle to power the printer.
You need at least 6 times the wattage. Call Samlex.com. This is for the surge and heat fuser. This is too expensive so I am going for a portable generator.
There is no power switch on the HP LaserJet 1000 printer.

Laser printers uses dry ink power
Bright, like all laser. It is about as bright as a low power laser pointer. It is usually a class one laser and can not hurt you, but make sure you check it's class before opening the printer, though I would not suggest opening it in the first place.
The two dangers that need to be avoided by a technician when servicing a laser printer are electrical shock and mercury poisoning. Laser printers use a very high voltage to operate, and contain a very high level of mercury.
Inverter efficiency varies with DC input voltage, ambient temperature, and operating power level of the inverter. It can mean power-out divided by power-in.
Laser printers can receive too much power from a UPS
It would be B. With a keyboard
Yes, provided the power inverter has a high enough power rating (wattage) for the CPAP device.
