I would look at buying a modern small networked laser that has low power consumption (look at the tech specs) and couple this with a decent APC UPS with the runtime you require. I have never seen a printer with a battery backup before (except a couple of portable HP inkjets).
This will save you a lot of money and will cost you hundreds and not thousands. You would have a spend a lot to get a UPS that can handle 700W continious load.
Before you spend out any money get a spare UPS and run the monitoring software on a PC attached to it. Connect the printer to the UPS to get the actual load. You might be able to get away with a smaller UPS than you think...
