can I take my inkjet printer and remote control in my carry on luggage??

Laurence, I am afraid that you may not bring inkjet printer on board because it has ink cartridge inside. If you take domestic Chinese flight, you can take the inkjet printer with you to board the plane. However, you should put ink cartridge in your checked luggage. I am not sure if the airline you choose take the same policy.

I think you can bring remote control car on board. However, you should know that batteries are not allowed to be put in the checked luggage considering of safety issue. If you need them, you can bring them in your carry-on luggage on board.
