Hi Gail! Sounds like a fun project. It should be no problem to disconnect all the wires and pull away-shut down computer and power down printer first. If it’s just a couple of plugs (the surge protector, the phone jack) that are actually connected to the wall, then you can probably disconnect those and pull the whole rat’s nest o’ cables away from the wall. For protection from the painters (and paint), probably best to place in a large box, but if that’s not possible, placing a tarp over the ‘setup’ and garnish with red flags and a couple of those highway safety flares should get their attention! Paint on cabling and/or equipment’s a drag-Good luck!
