We do event photography coverage also. so we have to do instant printing. normally we do removing camera's chips and copy pictures and print it. That is very difficult thing and time wasting.
So I try to connect all the cameras as the picture attached. I could connect only one camera because Canon's EOS Utility can manage One Camera. so how can I connect other cameras for that.
I appreciate if someone can give a solution for this.
Certain Eye-Fi SD cards can achieve this to a degree. It looks like the Pro X2 cards might be required and you may only be able to transfer one at a time, but that may not matter to you.
As noted in the Pro X2 specs:
Infrastructure Support: Transfer photos from multiple Mobi Pro cards directly over configured wireless networks without disrupting your internet connections
See this discussion for more information about using an Eye-Fi in this way: https://community.eyefi.com/eyefi/topics/can-2-cameras-using-eyefi-connect-wirelessly-to-a-single-computer
Also note that you won't be able to use the Canon software(Camera Connect; EOS Remote was discontinued) for this unless you are the first known to hack it to do such a thing.
I just answered a similar question here: https://photo.stackexchange.com/a/72846/20519

It takes a TPLINK MR3040 (which looks awfully similar to the camranger!) and provides a dd-wrt firmware image that puts some kind of API onto the device that DSLR Dashboard uses. DSLR Dashboard appears to be available as a PC app, as well as IOS and Android.
I recently bought a device, changed the firmware, and tried it out with an iPad. [...]
