Printer Mac Wifi network connection

Since you mention the desktop running Win7, are you saying that the printer is being shared by this PC? Or is the printer connected to your wireless router and you mean that you have no issues printing to it from the PC?

not much info here. Was it working before? What have you done? How dod you "find" the printer? What driver are you using? Is it compatible with 10.9?

You've said pretty much nothing, sorry, just pointing out how little we know.

Sounds like you need to configure the printer to be browsable. Did you follow the set-up instructions for printng from macs?

You really need to ask Kyocera. Most printers are only browsable if they support some kind of local broadcast protocol that the mac can see - such a bonjour or, on older networks, appletalk. If not, you'll rarely see them (e.g.; old HPs) and you need to set their IP address, adn print to that address.

Still pretty minimal info.

Looking at the specs for this model there is no mention of Bonjour support. So you will need to manually add the printer to the Mac. To do so, you will need to know the IP address the printer is using. You should be able to print a network configuration page from the printer. Or you can refer to the Win7 PC's by opening Devices & Printers, selecting the Kyocera, right-click and select Printer Properties, then the Ports tab. In this list, the IP address will be shown (you may need to widen the Port column to see the full address or press the Configure Port button).

Once you know the IP address, on the Mac you can open Printers & Scanners and click the plus button to add. Select the IP icon and then enter the IP address of the FS-C5250DN. Change the Protocol to HP Jetdirect-Socket. Leave the Queue blank. Change the name to C5250 and leave the Location blank. If the Use menu does not automatically select the FS-C5250DN printer, click on the Use menu and then "Select printer software". From the Printer Software window, select the FS-C5250DN and click OK to close this window. Then click on Add to complete the printer queue creation. Now see if you can print a document from the Mac to the printer.
