USB hub with multiple printers

Hi all, At work I use multiple printers on my computer, I do a lot of shipping, I use Fed X ship manager and UPS World ship to do a lot of small package shipping. I have two zebra thermal printers currently hooked to my office computer along with a Brother HL2280DW, All usb connected. I would like to free up at least one, Possibly two of my USB ports, So my question is if I get a USB hub can I plug possibly both of the thermal printers into it? Not sure if since the hub is plugged into a single port it will cause a conflict between the printers.
Currently my printers show Zebra 505 (fed X) USB 1, Zebra 455 (UPS) USB2 and the 2280 is USB 3.
Really not very experienced at this stuff so any help would be appreciated.

You'll be good to go with a hub. I'd recommend a powered one from plugable, they seem to make decent stuff.
