Have desktop want to convert to wireless if pos to wireless printer?

If your computer did not come with a wireless card you must install one. Wireless is hardware (and software to make the hardware function). If you can no longer locate a carrier & card for your iMac you could use a USB wireless Dongle.

HOWEVER if the wireless printer is on the network, and you have the drivers for that printer (unless they do not go back to 10.4 (we are at 10.9 now-that's 5 generations)) your computer should "see the printer" not vice versa.

You set your computer up to use a printer, not a printer up to use a computer.

You may need to seek local professional assistance to figure out your solution.

Good Luck,
