Should be able to find some answers here.
But you should be able to plan based on the rated standards on the devices. Remember your laster printer doesn't use too much power on standby, so that should not be the main factor. If you want a Desktop protected by the UPS, then don't use the UPS to feed the laptop. Just plug the laptop straight to the wall. If power fails, the laptop will just use the battery. Really just buy a brand name device like APC, and you should be a happy camper.
