Jet combo Planer/Thicknesser

Hi Guys probable a stupid question but one I just don't know the answer to due to being relatively inexperienced. Would a Combo Planer/Thicknesser also work as a jointer or am I barking up the wrong tree. I have limited space so I'm trying to plan ahead with my shop fitout and looking at machines that may do multiple jobs but taking up the same amount of floor space.



Thanks
