How to print part only (instead of to print all)?

Hi All,

I have problem to print some part of a drawing. Let say I have drawing as the picture below. But Instead of to print the whole drawing, I just want to print partly based on the need (i.e I just want to print the 4 component with red and the blue color). But after I tried many times, then I gave up, I failed. My question, is any way to do that thing? Or should I have to move it to a "temporary" file so I can print?
 

You can't select certain entities to be printed only. You could place these entities on extra layers and then set the other layers as not to be printed in the layer list.
Or just delete the unwanted items and after printing make an undo. Feels risky but isn't really.

OK Dellus, thanks. I normally just select the part I would like to print and just paste it to another temporary file. It is really work not risk anything.
