一个夏威夷Customer 买了个打印机，后来还是给他寄了，但是今天收到4分FB并留言如
下，该怎么回复好？
I may have to return my unit to the seller. He did not send in the box a
signal cable. I cannot turn the printer on with the instructions furnished.
The view window in the printer has none of the words referred to in the
instructions. There is no instructions re how to use the CD. I need a better
step by step instruction that matches what I do not have with the present
instructions. I need help! Thanks
