Convert Hp 2175 psc to wireless to enable wireless printing on network?

I have a HP 2175 All-in-one printer. It is connected to my desktop and sharing is enabled. I have 3 other laptops and every time i need to print something from them I have to turn on the desktop and then print. I need a solution to be able to make the printer wireless. I know there ae plenty of wireless print servers out there but i'm wondering if investing in one is a smart choice or just buying a new wireless printer should be the way to go. I love my printer and it is quite economical so I don'tt want to give it up. Any suggestions and advice would be welcome. Any cheap and affordable solutions would be highly appreciated.
