Heheheheh.....I guess it depends on a few things......such as the location of your printer, pro/hobby, etc.
Since my printer is located in the "office" of our home which is shared with my better half, if I put a trash bag over my printer, my wife would have both me and my trash bag covered printer out on the curb!
LOL.....
YMMV

A simple bed sheet would work nicely. Or even a bath towel.
