Can I connect a Laser Printer or Office Multifunction fax/printer to my UPS?

in FAQ

It is not recommended that you use a UPS on a laser printer. Laser printers have a large heating and sealing component that can draw up to 1000 watts. Therefore you must have a greater VA rated UPS to do the same job. This makes the UPS backup of Laser printers very uneconomical.
