Help with connecting desktop to wireless printer

Hello can someone help me out here. I have a small office network of 3 desktops and 1 server networked. I do not have wireless on the network at this point. I bought a cannon printer that has wireless abilities. Can I just use a USB wireless adapter, netgear N150, and put it on the desktop that is in same room as printer and have the ability to print from that desktop, wirelessly, with the cannon printer?

 

where is the router in relation to the printer? Can it not be plugged into it? Also you could use a network switch between the pc in the same room and the ethernet cable to allow you to plug printer directly into the network. Either of these options would allow any PC on network to print anytime. Or plug it into any 1 pc as normal and allow sharing in printer options. You can then print from any PC as long as the PC the printer is connected to is switched on.
