Surge protectors are considered to be a cause of fuser error messages for some
laser printers. See http://www.advancedlaser.net/errorcode/error_50.htm for one
side of this debate. I am not going to get involved with the debate here
because neither side can win, but be aware that there IS a debate and I have
seen situations where bypassing a surge protector eliminates 50.X fuser errors.
The original post was about a power strip however which is a very different
beast and there is no evidence that these cause problems.
